"You have to start out as a mop man. It was also called a scum scrubber, a jizz mopper, or a sperm swabber. You had to disinfect the booths quickly so another guy could get in there. Customers would spend more if the peep booth was clean. Our slogan was You drop it, we mop it."
Awww, I'm coming over all nostalgic!
