Oh they don't appreciate it? I'm sure they appreciate it when you are shoving 1's in their thongs...
I'm sorry, I've never been to a strip club (honest, and i'm 23), but IMHO if a women is willing to flaunt her body in such a fashion she has already disrespected herself and should get over the fact that a few paying customers are trying to get a keepsake of the night. If you don't want to be seen naked... u should probably get in a different business...
