There are hustlers in all walks of life....including strip clubs (
surprise!

).
From personal experience, I've had varying degrees of relationships with several strippers from mere acquaintances, friendships, pure sex to a multi-year, live in relationship. I met all but 2 in strip clubs.
Most of these chicks don't stop being regular women with regular women wants and needs just because they strip. Depending on their lifestyle, they have sex and relationship wants and needs too. Certainly they don't go to work looking for a relationship with a guy they meet there but it absolutely depends on your approach.
Frankly, if you go into a strip club and grab up the first two or three chicks and do a ton of lap dances and the most interesting thing about you is the drool sliding down your chin...you are a customer to them and they are a fantasy to you. They will most likely want to keep it that way and the biggest way to upset that is by ruining the fantasy and doing stuff with you outside of the club.
There are some chicks who play for pay outside the club by doing "private parties/shows" with just you and her.
There are some chicks who don't want to date anyone seriously while they dance for their own, obvious reasons. The point is most of them are just regular chicks from what I've seen.
Honestly, with some chicks a $20 (or whatever) tip out of nowhere without a lap dance gets you more mileage and credibility with them than a $100 worth of lap dances would.
Never loan or give money to anyone you don't know well enough to trust...stripper or otherwise. Never loan or give more money to someone than you're willing to walk away from. Live by those rules and you likely won't feel or get duped by anyone.
