I actually suspect it could be this:
1. Customer shows up at shop expect hot, raw sex.
2. Goes and meets the girl, who drops his pants and sees strange growths and shit all over his crotch.
3. Girl requests he wears a condom. Customer gets visibly upset but of course obliges the lady.
4. Customer blows his load in the rubber, leaves, and complains to manager. Asks for a refund or voucher. Manager refuses to compensate.
5. Customer decides to rat out the shop.
I believe this is the most likely scenario, because it’s almost glaringly obvious what kind of business the shop is conducting. Something of similar nature happened to one of my favorite shops recently, although they dodged getting shut down likely by vouchering off the customer threats.
