If a stripper will only spend time with you when you are spending MONEY on her,

There's a difference between being "friendly" and being "friends". Customers are "friendly" towards certain dancers because we think they're hot, and enjoy spending time with them. Dancers might be "friendly" towards certain customers as they feel comfortable with them, and of course have money. Being "friendly" in a club is part of the game. Of course if you're truly "friends" with someone, money doesn't matter.

She is at the club to make money regardless of whether she really likes you are not. Even if my favorite didn't ask for a dance I would at least give her a tip because if I didn't want a dance that is time she could have been making money from someone who wanted one. my curent favorite doesn't ask for any dances when she comes and sit with me but I usually get one anyway. Recently I have stopped getting the lapdances at that club(Charge 35.00 for 1st dance 20 for 2nd) and get a 10.00dollar table instead. So either way I will give her a little something for her time.
