I have repeatedly said on here, and often received stick for it, that you do not owe the girls '
respect', you owe them
politeness: which is what any human being owes another human being.
The basis of any interaction is your punting experience, the session time you pay for. Interacting with favourite prossies outside of that is up to you if it improves your paid-for experience (and you are aware of the dangers). It is a ridiculous suggestion, in my humble opinion, that the alternative to chatting is being horrible to someone. Simply be polite, no more, no less.
Prostitutes are often quite 'needy' people. They have few real friends except maybe one or two other prostitutes and live most of their life as a lie, unable to explain their income or job to anyone. They have a certain freedom that disposable income brings but that is not the same as human warmth. So sometimes they kid themselves (the way some fluffy punters do). They persuade themselves that a certain punter is 'more like a friend': but then they are having a birthday party and realise they cannot invite their 50 yr old friend to meet a house full of 20-yr olds with no convincing back up story as to why such a person is a close friend they have never heard of. That of course is the better scenario! The more probable one is that she sometimes unconsciously but usually consciously feel that it is 'good business' -- like a rather inept version of companies that send you personalised greetings by phone or email.
If you like GFE, just remember it is a temporary illusion, one that you are paying for. It's like a contractual arrangement where she pretends and you pretend in order to heighten a particular type of paid-sex encounter. Such a punter would be advised to enjoy it if he must, keep it fair and polite: but be ready to let go at a second's notice.
