Many reasons for refusing to meet;
Someone rude on the phone - if you are rude and impatient what are you going to be like in the room.
Requesting A levels or similar tha'ts not on favs list and going "Oh well I suppose its not that important but if you change your mind when Im there" so your going to hassle through our time.
Haggling then saying I will pay full price.
Coming across like a pimp on the boards telling people to only see hotel escorts because the apartments are all brothels > pimp suspect for hotel escorts alert.
Thats the short list too busy not working or playing to list more
