How much would this hurt a stripper's "feelings"?

Take a girl (whom you've had prior experiences with)back to a timed VIP room and tell her that you're not having a good time because she isn't dancing to the style you like (sultry, sensual, facing me and touching v. grinding, back turned and hands-off). Even after telling her multiple times what you like she still struggles to do much about and you leave the club spewing profanities because the experience was so nightmarish.
Fast forward to last night and she is back at the club she was allegedly fired from a few months before. You entertain her and her friend and get dances from each. The friend is enjoyable and then it's her turn: you lose your erection and are seriously tempted to juss tell her to stop midway through because the dance was the worst you've ever had. You mention the prior times and how it was disappointing. The friend comes back with well they couldn't be that bad since you were a repeat customer. I say that I was hoping to get her to do what I prefer but it'll never happen. I sit with the friend explaining juss how dreadful the prior time was. The girl I was critical of never even acknowledged me the rest of the night (no loss) and blew right past me as I departed for the evening.
Is it valid to offer constructive criticism in this manner? I did specifically say that it was a problem dancing for me and that other people may really like how she grinds with her back turned.
