a cleaner stationed in the public toilets, who stands there kinda stalkery, closing the cubicle door right after the person in front has left, so you then have to pay her to unlock it for you

I'm Finnish, and when I visited Germany that was one of the biggest WTFs. I called them Toilet-Pointer-Men, because in most places the only thing they did was to point at the door and then hold out their hand for the tip.
