A good client is a good client, I would welcome him regardless who else is he seeing. My understanding is that we are here to provide a service and for many people variety is the spice of life. The good clients would pay the stated fees, would be nice and polite, friendly without getting too personal, would understand that if an escort has already a booking she is not going to stood another client up just because they want to visit again etc... I am normally happy to see if those clients have a good time with somebody else, I feel sorry if they had a bad time and I am looking forward seeing them again whenever they are ready seeing me again. If for some reason this never happens, so be it but from my personal experience, this happens very rarely, eventually they are coming back.
But if clients asks for personal favours from me while they are happy to get much less elsewhere OR
if they make a lot of personal favours to others while acting cold with me (still visiting me though), I could start getting annoyed. The more the annoyance lasts, the less inclined I am to ever accept their custom again.
Reviews usually make me annoyed, when repeat clients continue to visit me but they never leave a review, while they would review others. I understand why someone may not want to leave a review, but then why still come seeing me? I feel discriminated against. Repeat clients that ask for discounts also bother me when they would try to save a lame 10 Euro on me but would be quite the big spenders with others. In certain cases I feel really annoyed when I see that those clients see pimped girls or girls I suspected of doing BB sex
and in those cases I immediately refuse any more visits.
