I would like to share an experience and find how the men and ladies feel about.  I want to hear from both sides...

Women are still emotional creatures even in the hobby. It shouldn't be that way but it is. If you were a great client and the only issue was that you canceled because you were anticipating a double and not a single, well there is nothing wrong with that. Drop her and I bet she will be contacting you again sooner than later. Some ladies get upset by your choices but ultimately, they are your choices. No need for drama or explanations. ANGTFT!!!

I can see how she my have been insulted by your actions, You would see her with her friend, but not alone.  She would read that as you think she is not good enough. Then on top of it, you plan another date with someone else, and write a great reviews about her.   WOW talk about pouring salt on a wound.

is to avoid drama like this.  Its not needed at all.  You are free to purchase the goods and services you desire.  The provider is free to decline any suitor.  Its easy.  Keep it that way and move on. Good luck.

with you and the well reviewed lady?  Perhaps the 2 ladies would have welcomed the opportunity to make an acquaintance with another well reviewed lady.  This would have given you the new experience you desired without making Laurie feel slighted.  The 2 ladies might not have agreed to it, but it never hurts to ask!

I can see how you were disappointed and appreciate how she reacted. We are all human, regardless of what we're doing. We get frustrated and we can feel slighted. You both acted on these emotions. She's disavowed/ignored you now and this has caused you to second-guess your actions.  

You had the plans for doubles but they did not pan out. She is being childish removing your white listing. You need to backchannel folks to them know who she is to avoid. She has to understand that you are not her girlfriend.  

So he could take his time and enjoy her or maybe saw her for 2 different sessions that week.

I can understand her disappointment, but her reaction is somewhat childish!

You were expecting a double, and from what you've said, it took an email from YOU the night before to find out that it wasn't going to happen.  Did she know earlier, but not tell you because she didn't want to lose the date? (i.e., hoping you'd still stick with a solo date).  Maybe that isn't what happened, but when you only hear about the one lady bowing out after you email asking for confirmation, it would make you wonder and doubt.  If I was in this situation, it would make me want to look for a fresh opportunity, rather than go into the date with Laurie with any lingering bad vibe or doubt.  I'm also guessing this situation could have worked out differently had she let you know earlier.

she does not get to decide who you see

so now this is about feelings?  

it is an unnecessary road to travel down. better to avoid it altogether.

at least for me, is that you had to email Laurie to find out that things were not as you planned.  Now of course there is the possibility that she would have told you pro-actively, but the fact is that she didn't.  And she didn't offer to find a replacement either, which would have been nice.  That said, I think in this case, that sometimes we have to do what is right and not commit a felony because someone committed a misdemeanor.  What she did was bad communication, but I am afraid what you did was hurtful.  

a kick in the gut if a lady sees another trick?

ok

this is how i'd feel.

Well, what I said was the kick in the gut was a result of the entire scenario you quoted, not just her seeing another trick.  But that said, and maybe I'm on an island on this one by myself, but if I had to wait to see if a provider was unable to book a session with someone she wanted to see more than me before I got my chance, and I knew that was the case, that would not be my idea of a good time and I would politely decline the opportunity even if my number came up (and yes, I know that happens behind the scenes so maybe it's at least more honest that the lady you're talking about at least is up front about it).  But maybe that's just me.  Good for you, though, as it clearly works for you.

do you usually see ladies for longer than one hour? 2,3, 4 hrs?

Ahh, yes, I usually do two to three hours.   I have not yet run into it yet, but I'm guessing it will probably happen one day.  Good point.
