Wait, why is HE the worst? Even if the take the easy way out and totally ignore that all three were in some seriously deranged drag and participating, You are the person working in the place with not only the pervy costumes provided in house, but also chained dog collars and who knows what else? You provide a full smorgasbord of degeneracy and have the gall to act shocked, when a customer takes part in some of the tamer options (she didn't see the all-but-SM stuff).
That's like running a meth lab and then being outraged that there could be narcomaniacs in your city. My girl, you dealt it.
