When they phone and are polite and seem fine but then when I ask when they would like to meet me (because they have not mentioned it!) and they say oh not really sure/maybe next week/what do you suggest etc.

I quickly get rid and just ask that they contact me again when they know which day/time they want. It smells of timewasting to me at this point. I suspect they are just phoning to hear how I sound.  I log them in my phone with a signal to myself that they seem dodgy so be aware.   

One of the most common reasons for not accepting them is if they say a mate/friend gave them my number. 

Anyone who is over or underwhelming, either bombarding or sounds like they can't be bothered.

Yes I can't stand pushy men or vagueness...If they don't know what they want how the hell am I supposed to   

Had one today. A new client asked if I would be extremely submissive, I said I don't offer this kind of service I offer GFE. To which he stated that was fine and asked where I am based.

1. How can you go from asking for something (I would call) specialised to being ok with a vanilla service
2. Read my bloody profile, it says exactly where I am!

Yes, I second all of this.
These are the 'stealth 'timewasters that we give credence to as  newbie ( unjaded ) Escorts, but can sniff them out a mile off with practice.
Had one this week calling from AW, telling me he's booked a lovely, posh hotel for later that evening, but stuttered when I asked which one? Didn't have a time he intended  to check-in, but wanted to assure I wore certain lingerie..Of course he never confirmed..Callers who got my number from "a friend" somehow can never remember which friend or anything about them..I entertain myself by firing lots of quick questions about their "friend",  booking location, check-in time, domestic discretion situation ( if home visit ) and visualise their hard-on slowly diminishing as I speak 

I except booking by text but definitely not if they Message me saying 
 
Can I c u l8tr or r u available

If they text me asking 'Do you wear heels?'.  Quite what do they think we wear?  Army & Navy gear or what??

I just ignore those ones.

And 'Can I request you wear stockings and heels' Err I wouldn't dream of wearing anything else, I thought that was standard attire for an escort 

But having said that I've done 3 somes with other escorts who I've not met before and they've arrived at the clients place having not got dressed up at all, one off the top of my head was wearing a pair of battered old trainers, no stockings, no make up at all and greying old/worn non matching underwear, so can sort of understand their concerns sometimes. (btw this client wasn't at all bothered)

A conversation with a vile creature the other day:

Him: I've seen your ad online wanting to book 2 to 3 hours
Me: Oh right what are you thinking of doing for 2 to 3 hours?
Him: What services do you offer and how much
Me: Its X amount for one hour, what services are you looking for?  if you're looking to book for longer then its more of a social meeting, not constant sexual activity for that length of time, trust me nobody would be able to fuck for that long, man or woman.
Him: Oh well I want roleplay and to use toys on you and to keep making you come
Me: No that's not the type of booking I offer, I'm not interested
Him: Ok then for one hour?
Me: No thanks I'm really not interested.
Him: Well I'd like to book you
Me: I'm not interested, bye.

Cuts him off.
