Nadine's customer 'experience'?

Ok. Nadine tells the girls about the time she had to give a bikini/anus wax to a woman who keeps wiping herself off with tissues, then apologizes for "leaking" all over the place.
I'm sorry, but I kind of don't understand. Was she leaking what I *THINK* she was leaking? You know, from being a whore, and all.
Or something else?
I hope this post doesn't get deleted, because I'm curious. :(
