“They don’t have to do it” is a poor argument if “it” is ill defined or suffers from scope creep. If “it” starts out as “waitress this event” and ends up as “keep your mouth shut about what happened” then something has gone wrong. It’s not comparable to stripping. No one goes to work at a strip club then gets upset at the idea of getting undressed. They might get upset, however, with punters looking with their hands, because that is not generally part of the agreement. Likewise a prostitute might get upset if she accepts money for deed X but is forced to perform deed Y.They don't have to do it. The same way women don't have to work in strip clubs. Or dance in little more than their underwear for bands. Or heck...some of the band's wear little more than underwear.
Some don't even wear that.
You have women like that Kardashian thing who are only famous for being *****!
