Don't judge a book by its cover

I've gone to strip clubs and come across dancers that had the perfect look only to find out they are not good dancers or have "funk" issues. Then there are dancers that are average but give outstanding dances. I think the ones that have the look seem to rely on that and don't do anything beyond. So in general I keep my options open. That includes personalities. Personalities that are messed DRAMATICALLY brings the quality of a dancer down in that if she isn't pleasant chances are it would be a waste getting a dance from them. Have any of you ever been so excite to get a dancer you finally wanted only to be so turned off that you either cut it short or after the time spent you didn't want to deal with them ever again? What was the deal breaker?
