I used to dance and know girls who dance now, and yep we definitely did our tricks! But when you're dancing 15 min stage sets, for 8 hours, obviously you have to pace yourself and can't bust out non-stop aerial antics all night!!
But the truth is most men don't really appreciate it, as some others have said they tip more when you're up-close-and-personal, not huffing and puffing somewhere up near the ceiling, your hair and make-up getting ruined as you try to pull off some amazing trick!
Also thought I'd add that from my experience, the female "customers" were often the nasty ones who were basically there to judge you, thinking (or worse, telling you!) they were prettier/thinner/could dance better, and understandably also maybe feeling threatened because their guy's attention was diverted to other naked women! Plus, to be blunt, couples were usually just there for a novelty and didn't really spend $$$.
Not saying you're like this, Nymphdancer, but maybe the dancer at your local club has been treated this way by others, so now she is guarded towards other women?
Hope this doesn't come across as rude! I have a lot of respect for strippers, it's a tough job and it is also one place our art originated and I think we should celebrate that! :)
