From early on, the "rules" were made clear to me;

I come home a few times and realized the envelope was still in my pocket. Each time the ladys were totally chill. Your lady sounds BSC.

I used to have a habit, at least with gals I knew well, of leaving the envelope after, not before, the date.

I usually say something like "this is for you" when I put the envelope down. Doesn't necessarily imply anything indiscreet, but it focuses both of our attention to the fact that it's been delivered.

but something like this never happened to me.  Without knowing any other facts or circumstances I have to believe that the provider genuinely didn't see the envelope.  Perhaps in the heat of passion one of you knocked it over?  I would say that I have had a few experiences that did not meet my expectations but overall my time in the hobby has been extremely enjoyable.  I would look at the bigger picture and not get too upset over it.  Just my 2 cents.

ended with me very happy.  She called me later in the day telling me I had short changed her considerably.  I was not sure how this could have happened, but I felt very close to her and asked how I could get her the money. She had me go to a post office or a bank (I don't remember it was a long time ago.) I did so the next day and made sure she got all he money promptly.  
We became (in the hobby sense) fast friends and I enjoyed her company in different places many times.  I never want a few dollars to ruin what could be a great relationship

I always make sure there is eye contact while I place the envelope, or if it's incall I put a bottled water or something on the donation and mention that it's for her.  Haven't had a problem yet.  I can't imagine how awkward it would be to leave with the envelope still in my pocket

There was this one provider I had seen reviews of and photos who was totally wild but based out West.  One day I see a post on TER that she is coming to my city. Couldn't fucking believe my good luck. I sent her an email and we set up an appointment for a morning romp.  I had an envelope with her donation all set and was about to head out when I couldn't find my car keys.  Frantically searching for them I must have put the envelop down without realizing it. Eventually found the keys and took off because I was running a bit late and I knew she was going to be busy on this visit.  Get to her hotel on time and she texts me her room number and up I go. We have a great session and I reach into my jacket pocket and No Envelope. I'm quickly checking all my other pockets and no envelope. I really started to panic. I had to tell her and wasn't sure how she would react. I had noticed an ATM in the hotel lobby on the way up to her room.  So I offered to go down in the elevator, get the cash and come right back up.  She, to her credit, was totally cool with that.  I offered for her to come down with me and she said she had to prep for her next client and that she trusted me!  I go downstairs and lo and behold the ATM is out of service.  The nearest one was 2 city blocks away.  So off I run and hurry back.  Probably took 20 minutes.  Meanwhile I start wondering if she thinks I just ripped her off!  I go back to her room and knock on her door and she opens it stark naked!  I tell her sorry the Atm was not working and she just smiles and kisses me and takes the envelope and says see you next time!  Gotta say she was a class act on the whole thing!

As I entered her house, she took me into the bedroom through one route. I placed the envelope on a conspicuous room divider space, visible as hell. After a rather rushed poor performance, with restrictions contrary to her ad, she took me out by a different way and said, "Where's my damned money?"
"Right where I left it!" Needless to say, I never saw her again. By the way, her age was about 10years older than advertised and years later she is still advertising the same age.

Obviously her brief reply to you was insufficient.  If she is someone you would have liked to see again (barring what happened), you might consider letting her know your thoughts about her reaction...and be up front about it.   People do make mistakes.   I'd be inclined to cut her some slack IF you receive another message from her that is more thoughtful and sincere, but that's just me.

LOL

I drove 80 miles into the big city to see a provider.  She came down from the hotel room to meet me and let me up to her room.  Walking to her room I realized I left the donation in my vehicle.  I had to excuse myself before the session to get it.  She thought I was dumping her because I didn't like her.  She went ape shit with the texts when I was in the parking garage.  I could not console her and had to leave.  That fucking sucked!

I was mentoring a young lady who was applying to law school and wrote her a note congratulating her on being accepted to her preferred law school placed postage on it and placed it in the passenger seat next to my donation envelope as I was going to see a provider and thought I would post my letter on the way home

..to my hotel while traveling.  Placed the envelope on the bathroom vanity where I thought it easily seen, and she excused herself to the bathroom shortly after arriving.  After the session was over, and she was ready to leave, I handed her a folded bill as tip.  She took a quick look and says "what the heck is this?"  We are in a direct sight line with the bathroom vanity through the open door at this moment.  I simply pointed, she turned, immediately saw the envelope, showed obvious embarrassment, and stammered an apology.  No big deal, but made me wonder if she had to pee so bad that she forgot to check for the envelope.  Or hey...maybe she was so excited to see me (she was for sure enthusiastic about what we were doing) that she just forgot to check for the envelope.  LOL

Exactly the reason I have never used one.  
My donation is in a pocket all by itself so it's never confused with what I plan on tipping.  
The envelope system has always seemed stupid to me and frankly I'm not storing envelopes  
Nobody has ever complained or mentioned it but I'm a friendly and easy to talk to anyway and have had some lackluster meetings but none uncomfortable.

I do the same as you and simply put the exact amount of the donation in one pocket and the rest of my money in another, the day that I can't remember which is which I suppose is the same day I need a keeper. It's not that fucking hard.

I suppose you can't fix BSC either.

... that the envelope is to be put down discreetly, in a specific place, and never to be mentioned or alluded to or the date will end immediately.  Not sure if that was the case here, but saying something like "this is for you" in that kind of situation could result in a really short date!

I worry more about the right amount since the web sites are often inconsistent , special services charges, special amounts, and special end dates.    One even charged extra for BBBJ.     I could not find that on the web site.       On some providers it's hard to even locate a donation on their web site.    Always worked things out fairly with every one happy.

I do the same.  
I never leave it on the sink, always leave it on either the nightstand or credenza.  
When I've done in calls to what is obviously her home I look for someplace conspicuous, make eye contact when I arrive and say "thank you". No other comment necessary.

once when i met a lady she was so hot we started making out on the sofa and then she had to remind me about the envelope which was still in my pocket.

we give to the lady........we leave it on the bathroom vanity, VERY hard to miss.

yes i always make sure the lady sees me take the envelope out and put it on the counter.  with women i know i usually refer to it "this is for you" or "dont' tell mommy i give you such a big allowance" or "here's that insurance payment y ou were waiting for" or some other nutty gag.  but only with women i have seen before.

dude i'm based out west name name or it didn't happen!

Happened about 8 years ago. Her name was piper

Many times at outcalls to my home. It is always in the bathroom where the ladies go to freshen up before the playtime starts. It has never caused any problem and most times they leave the empty envelope to be used again LOL

her incall I will place the envelope on a counter or nightstand, put my cell & car keys on top and then go wash my hands. When I leave, I pick up my keys and cell before saying goodbye. In some of not most cases, the envelope is still there.

This is definitely NOT the motto of JDU.  

Shame the rules are so silly here. In Oz the guy can just hand over the $$

The many rules here make my head spin as an out of towner. Used to it now but boy it's so much less tense and awkward in Australia where you're not on tenterhooks wondering if you've got the etiquette right. Someone came to see me in Chicago and when I answered the door and let him in I forgot myself and gave him a hug, and he then freaked out saying I must be LE out to entrap him because I touched him and seemed too 'friendly' !!! Shook me up totally and made me nervous which made him even more nervous and he left!!

Some of my best experiences were when we didn't even come up for air to even introduce ourselves until thirty minutes in when we finally took time to take a breath.

I put the cash in an envelope and on the front I write....To [Provider] from MintyFreshness.

I have seen this gentleman probably a year and a half, and it has happened 4 times where we forget about the envelope, because we are so into the conversation prior to him leaving.. But he would put it somewhere either too high for me to reach, like my shoe bookcase or under the side of my computer which of course it's hard to see clearly if I'm not looking there.  

He had an otherwise great session, got his rocks off and then let a few minutes of stress ruin the whole thing for him.  Whose fault is that?

one totally stunning lady had me so flustered...  that I forgot & she did have to ask me.  Her set up was such that my clothes were on a chair but not in the room...  & no convient place for my pocket stuff...  so I devoluped a system...      
I put a paper clip on the donation & put it in my key pocket so i can't get my keys out without feeling it.  But unless she requires otherwise, I put the donation on the dresser next to my clothes when I empty my pockets when I undress...  just like i do anywhere else.  When I redress, the donation is left behind.  Most of my gals are fine with this
I had one MILF get freaky & swoop in on it as I redressed, afraid that I was going to put it back in my pocket...  kind of wierd as this was the third time I'd seen her...  But it was hers & no harm, no foul...  the session was ok but when I came out of the bathroom she & her GF were puffing cigarettes & not GFE goodbye so I lost her number after that.  
Once I decided at the last minute to leave my jacket in the car...  and the donation was in the jacket pocket.  I knew as soon as we were in the room...  It was a Fav lady...  I offered to get it or send her to get it.  She declined.  I was her last appointment that day & we walked out together.  I put the jacket on when we got to the car.  Turned to give her a quick kiss, we clasped hands & the donation passed hand to hand.  We went on our ways...  
Yes, one of my biggest fears is that I'd forget to leave the donation...

Ive only had a couple revisits so far but I was pretty excited for the last one and put the donation in my bookbag that I carry with me rather than in my pocket so I could get it out the way. Ended up forgetting about it, luckily she caught it before I got out the door. She was cool about it but I felt pretty bad about it but not as bad as I would have had she not caught it.

Absolutely correct. I tell the guys to make no mention or reference to the donation or I will ask them to leave. But I also specify where to put the donation long before he arrives and I check to make sure its there before we start having fun.

What's a credenza?

As a short of time as I've been here on TER, I've already seen this topic come up before. Everyone has their way of doing it and they're all good ways, and funny! But what does it really matter? Why can't you just hand her the money? Or say here ya go? And sit it anywhere. Or if u do give her the envelope, u could say "hey I found this on the way up, it may be urs or ur neighbors"
Seems like unless you hand her money directly and say "here's the $300 for us having a fuckathon" it shouldn't matter!  

If anything it's more damning to have the exact amount of her advertised rate in an envelope than it is to simply have that much cash in your pocket.

When I first started out.  Same exact situation.  I felt awful.  Then she found it.  Never has happened to me since, thank goodness.

It's more connected, in my mind at least, to GFE.  By putting a fig leaf over the transaction it lets everyone pretend she's really your GF

The first time, got a text 30 minutes and said I was $100 shy.  I triple counted (my first outcall ever - so was stressed).  Many back and forths and she gave up.  Next morning, apology text saying the $100 bill was on the floor of her car.  Whew.
