The practical points of stripping

The audience often tips strippers by shoving cash into boots and waistbands, or so Hollywood would have us believe. Alas, at the age of 40, I have never been to a real life strip show. Husband was dragged to one by his uncles when he was 19 or something. He says they are depressing.

Anyway, what happens when the article of clothing with the waistband comes off? Where does the money go? One friend opined that the bottoms DON'T come off. True?

Secondly, suppose a guy is stripping. Body builders show off the definition of their bodies with oil. Does a stripper do the same thing somehow?
