No... unless you come off as being desperate and pathetic. They're just like girls outside of the club, other than the fact that they are taking off their clothes for money. If they're attracted to you, it doesn't matter how much or little you spend. I've been friends with more than a handful of dancers, some for multiple years now, and have seen just about everything in that business... in part because I also was a dancer (of the male variety).
I've had one tell me about an old guy who's currently coming in once a week, every week bringing her ~$500 a visit who she doesn't plan on sexing, and in the next breath asking me to introduce her to my friend so she can have a romp in the hay with him... and he didn't do anything other than come in with me and buy a drink (for himself).
Moral is, they don't care who you are, or what you look like. They're after your money and that alone. If you look good, or are extraordinarily smooth, then it's not uncommon to sleep with one within a few days to a week - because of their job, most of them have a very relaxed outlook on sex. I thought that I've slept with a lot of people, but when I watch one or two of my friends go it seems I'm a virgin by comparison. I wouldn't recommend them for long term relationships... hope this helps.
