If you'd asked us six months ago whether the world needed a bathroom janitor simulator, we'd probably have said no. We'd have been completely wrong of course, and as a result we might have missed out on the toilet humor delights of Men's Room Mayhem. Even so, a call-center simulator surely seems like a stretch too far. If you've worked in one, you really don't want to go back. If you haven't, then trust us - ignorance is bliss. So how does Smooth Operators go about charming us with this dreary slice of modern life?
