I'll start:

1. Receiving an e-mail or PM that only says, "Hey, are you available?"
2.  Any message that contains, "...how much for...?"
3. Random text messages or calls from new/unknown people.

I have more, but will leave the rest for others to share...

Happy Hobbying!

~ Asking me any question that could have been answered by doing your proper research.

~Contacting me for a date, then upon the day of date, asking me questions about rates or services. Then, of course, canceling or just stop of communication when you find out I may not offer something you were seeking. This does tie back into bullet point #1 of doing your proper research. If you schedule a date with me, you are my first and only date of that day. (I do not do more than 1/day, nor am I available as a companion all day, everyday)  

~Any message that has text type of writing. ("Are you available?" = "R U Avail?")

~When providing references, I only get a name, or partial name or a misspelled name. This makes it incredibly difficult for me to do MY research and find the lady. This is also why I ask for direct links to showcases/profiles.

~Common Courtesy. If we have never spoken before, do not just attack me with all sorts of questions without a proper greeting. A hello FIRST goes a long way.

~General Time Wasting/ Bullsh**ing. Time is one of those things that can never be recouped. I can make more money, but I can't get back my time. I do not waste yours, so don't waste mine.

Here are a few of mine. *curtsy*

4. When screening is complete, but I still have never met the person, they ask me, "What do you want to do to me?"  My first thought is, "I've never met you; I have no idea what I want to do to a person I have never met before.  I'm not a lady who fantasizes about strangers. Ask me the same question the second time you see me, and I'll be much more open to this."

5. Like GenesisNicole said, improper introductions qhen contacted.  I don't like to be bombarded with questions before a person has taken the time to say, "Hello, my name is...."

6. Contacting me via e-mail and telling me your handle or ID on a hobby website. If you are a member of a site, just send me a message via the actual site.

7. Messages asking, "do you ever offer specials or discounts?"  If you have to ask this question, you are not my kind of client.

8. Giving me reasons why you can't afford me, or screening with me, and then proceeding to say they will contact me in the future because they need time to save their hobby funds.

1. Not reading my showcase.
2. Not sending everything I need for screening even though it is  listed in my showcase and ads.
3. When the first message says "hey are you running any specials"
4. When they say "The modtards know me I don't have to have references."
5. When they ask "Do you see newbies?" back to peeve number 1.
6. Asking my donation when it is clearly listed on every site I advertise.
I can go on and on.....

9.  Asking if I do charity work for broke college students.

10.  While flattering, receiving messages just because they want to tell me I'm beautiful, without having any intention of ever booking with me.  Why is this such an issue?  I am prompt about repying and responding to appointment requests, reference checks, and screening tasks.  I could be at the grocery store with family, but when I get a message, I stop what I am doing to check it.  I could also be driving, and I will pull over to respond if needed.  

11.  Asking if I offer quickie sessions.

12.  Contacting me the moment they are finished readng a review on me, then trying to schedule immediately.  Once I start screening, they have second thoughts because they didn't take the time to do their research on my rates, requirements, and screening procedures.

13.  Trying to set up a new client appointment at 10pm at night and wanting to meet within the next couple of hours.  That's not enough time for screening.

14.  The words "hopefully, maybe, some day, some time, one day, eventually."  I don't believe in daydreaming about a future session; I believe in careful planning and execution.  Set a day and time, and follow through.

15.  Indefinite start times..."Hey babe, call me when you're free and we'll see if we can get together.

I can understand completely the pet peeves given by the lovely ladies.  It's a business for you and hobby for us.
Let's just say there are as many bad apples on both sides that spoil the fun on both sides.  I try to do as much homework as time allows.  Not all the information out there is reliable, I'm sure you would agree.
Here are some of my frustrations with providers in the past.
1.  Fake pictures, or old pictures
2.  Representing themselves as a certain type provider but subsequently with plenty of limitations not clearly documented, or simply stretching the truth.
3.  Waiting uncomfortably in the car while the provider is still getting ready.
4.  Passing the gentleman before me in the hallway.  Let your client know what your volume is...I like the provider who limits there dates to 1 or 2 per day.
5.  Doesn't every provider know the meaning of a girlfriend experience?
6.  Requesting further references when there are 5 or more listed for the gentleman on TER or P411.
7.  Asking for a tip...this should be done by the gentleman as is customary for any "good service"
8.  Counting the donation in front of the gentleman
9.  Forgetting the requested attire of the gentleman... I like a short skirt, stockings, no panties with 4 inch heels...what guy doesn't...and doesn't seem too hard, but less than half of my dates don't get it right.
10.  Just be honest!!
I hope I have not offended anyone.   Just wanting the Hobby to be a better experience for both sides.

10.  Finally, gentleman like providers to have a web site.  The gallery should have a complete album of pics.  We want to see the front "and" the backside...don't forget the backside ladies.  They should be tastefully done, dressed, partially dressed and nudes.   We would like to see would like to meet the lady before the meeting.

1. Misleading pictures.  
2. Misleading information
3. Misleading anything.  
4. Being businesslike and aloof instead of being congenial, flirty and friendly. (see also #8)
5. Asking for and/or counting the money.  
6. Using the phone.  
7. A messy incall.  
8. Poor physical preparation. (Please dress attractively, even if conservatively attractive.)  
9. No or poor IOP.  (see also # 4)
10.  Unreasonably complex verification requirements.  
11. Watching TV or leaving it on during the session
