I really think that prostitutes are worth paying for but sometimes they don't do a good job and I don't want to pay.

It sounds like you are interested in being a connoisseur of high quality sex services?

Yes I like call girls on the high end - not street walkers. But if I am paying big money I should be satisfied right?

For me the important word here is "satisfied".  Are you satisfied when the service is done well?
human
yes but sometimes its bad and I don't think I should pay - I almost want to just walk out.
The sex services that have the most “satisfaction” are ones where you are able to enjoy spending time with someone with a pleasant personality, even if they aren't particularly skilled in bed.   If you feel that you will be disappointed in a certain sex worker, you should feel free to move on to another one, whether that be from the same agency or a different one.  At the end of the day, you want to make sure that you will get the best experience possible.
If you’re disappointed by something that’s supposed to be good, the whole experience is sub-optimal.  Maybe it’s a sign that you should leave.  But if you’re curious why the experience was less good than you had hoped, I can help you explore that question.
