Same rules apply. Strippers and bartenders are pretty much the same. One is just slightly more willing to take her clothes off in front of a crowd.
I wouldn't tip her...but if she asks for a tip the proper answer is, "Tip? I got a tip for ya!" Works everytime!
True on the clothing. However, you wouldn't be involved in a long term relationship with a stripper/dancer even if she was everything you were looking for in a relationship? What if you were in a long term relationship with someone and you found out that they were a bartender/stripper/dancer/porn star previously? How would you handle it?
