I think that often, these guys just WANT a ‘dirty’ experience. They have the resources to address these needs discreetly without putting themselves in danger. But they don’t do it that way - Little Head ruling over Big Head.
Not about dirty. About anonymity. You mention “resources to handle it discretely”. They were trying to be anonymous, and walk into a Chinese massage parlor and pay cash.
it woulda been very discrete had the cops not secretly hidden a cam in the room.
