How would you handle this situation

You ask a dancer that is on stage for a lapdance and she says yes. You are already seated in the private room or booth when she comes in to give you a lapdance. She then asks you do you know the rules? as if you have never gotten a dance before. When you tell her yes she still persists to tell you what you CANNOT do during the dance(no mention of what you can do). Do you tell her after she gets through running her mouth that you have changed your mind and no longer want the dance or do you still take a chance on her?

I have had a experience like this in the past and sure enough the dance was as sorry as can be. To me when a dancer comes in and starts naming out all the rules it's a clear "Red Flag" that this isn't going to be a good dance. Strippers like this don't care whether you enjoy the dance they just want to get paid for doing the least amount of work they can get away with but still saying they provided a dance.

So what would you do? Would you tell her off? and what would you say? or would you try your luck with her?
