A few things that I've picked up from personal experience:
1) Refer to her as a 'dancer'. NEVER use the word stripper!
2) I've found that showing a real interest in her as a human being (not as a piece of meat to be leered at) works wonders. Ask her about her studies (a lot of girls get into 'dancing' to pay their way through school), her interests, her dreams, etc.
3) Don't bring up sex or how sexy she is. She's a stripper, she is constantly reminded that she is hot shit.
4) Avoid paying for anything (private show, drinks, ANYTHING). You don't want to be classified as a customer.
5) Be cool. As always
