@MissMushkila Sure, and I've been catcalled on the street, but that's not the same as being a stripper. Women are objectified and feel an obligation to be pleasing to men in all sorts of situations. The fact that it happens in the workplace (and, by the way, not just to baristas and waitresses but also lawyers and doctors) doesn't mean that doing those things for money bears any meaningful resemblance to actually having sex for money.
@WaityKatie Yeah, that part was interesting because it was the only piece of really blatant, unconvincing rationalization from a person who seemed otherwise pretty ok with the whole thing. Giving a stranger head and serving him coffee are not equivalent, regardless of the fact that he's liable to be attracted to you in either situation.
