When you have a regular need to open lots of doors – accessing equipment, supplying labs and classrooms, helping coworkers find their misplaced keys – the powers that be may be kind enough to cut you a master key. Saves time, effort, and several pounds of metal on a keyring. They are, of course, master keys with a limited range. Certain doors are off-limits.
The access door to the elevator-base maintenance? That’s a place we don’t need to be. It’s only important that we don’t stack anything of substance on top. (The roll of plastic seen here could be blown away by a light breeze.) Not that it wouldn’t be neat to have a look inside – after all, who wouldn’t like to check out some new kind of specialized machinery? – but if the elevator’s working, maybe let it be.
That said, it’s hard not to be fascinated by the accompanying light switch:
Sure. Of course. How else would you label it? Dark, forbidden basements should always get the proper horror movie styling.
And then there’s the nubbin of a switch. Makes one wonder. Can’t possibly be from overuse. (Can it?) Implies that someone did that on purpose.
Maybe the answer’s down in the pit.
