I think SOME guys don't realize that these women didn't dream of becoming prostitutes when they were children! This is a shitty job, even if all the johns looked like the actors that play Capt America and Thor, and I guarantee most look more like the jews who play Antman, Spiderman, or seth rogan and jonah hill.
Those poor women are, like most of us, working at jobs we can't stand, to pay the bills, so don't try to jew them down on the tip.
Put yourself in their place, how much would you enjoy your job and how much tips would you need to go down on roseanne barr, whoopi goldberg, gal godot, joan rivers or pretty much any jew, day in day out for years?
