When I worked in Bath, UK we had the 'Toilet Manager'. This was a chap in his 50s who dressed in a sharp, if old-fashioned suit, carrying a briefcase who every day would arrive outside the public toilets on the road where my office was based. He'd stand there all day, briefcase in hand, as if standing guard by the door of the toilets. He never went in, never stopped anyone going in, or never made any contact with anyone using the toilet. At the end of the work day, he'd march off again.
Eventually he was asked to move on and so took up a post outside of the local pizza hut, doing exactly the same but with a slightly pissed off expression on his face that he wasn't allowed to stand outside his beloved loos.
