Going get shot down here.
I know there are many mean and horrible men who treat prostitutes as trash, who treat anyone as trash. However there are lots of reasons why a guy comes to see a prostitute, maybe he wants to play out a fantasy his partner is not keen on or he does not want to share it with her, secondly he might be lonely
if you treat your clients just as a business transaction how do you expect to be treated well?
I am also curious if you have met someone several times and they are nice to you how do you not build up a personal relationship with them also,
