I used to work in Australia in parlours and we had really bright "checking lamps" in every room, we'd have the guys stand next to them and drop their pants at the start of the booking before any money changed hands and do a really thorough check. I guess the guys were used to it because it's standard practice over there. You wouldn't believe how many guys I had to turn away, on a Fri/Sat night in Sydney probably one in five guys, Melbourne men seemed a bit cleaner, prob only had to turn away one in thirty. I saw a couple of HORRENDOUS cases of warts, I'd get another girl in to "double check" so the client didn't think I was making it up, and we'd both point out the numerous warts covering his penis and he'd be like "ooh yeah, gosh I've never noticed that before, how strange", eeew!
