All of the above comments are entirely fair enough with the honest pro$$ie and punter, the problem arises where profiles on AW are so varied and apparently nearly every one is inaccurate somewhere.
I'm afraid that even with an apparently straight and established Brit pro$$ie with a well sorted profile the punter has to ask so many questions to finalise an appointment, that's before we even start on the non Eng speaking ( thick Brits and foreigners ) ones.
Do you charge extras ?
Do you smoke ?
Can I shower at yours ?
What is your nationality ?
How old are pictures and what is your body size currently ?
How many years ago were you your stated age ?
Where will you be located and when ?
What type of premises do you work from, is it a parlour , hotel , shared flat, private residence or industrial est ?
Is your location as discreet as you say, please describe the entrance system ?
How is it best to contact you reliably ?
All of these details ( and no doubt more ) have in my experience from one time or another varied from those stated on profiles and need to be checked before a booking.
