Not only since Elvis one of mankind’s greatest fears is to die while on the toilet. It’s hard to think of a less dignified place to spend one’s last minutes.
The second greatest fear and probably the only reason humankind ever decided to invent ways to create fire and thereby artificial lighting is of course – being eaten by a grue.
Now for whatever strange architectural and/or psychological reason someone decided to turn our office toilets into a torture chamber that combines mankind’s two foremost fears.

As you can see, if one is minding his own business, at any given time it might happen that someone switches off the light. And yes, there are two door between the business man and the bringer of darkness. Sometimes this is enough to drown out all kinds of heavy cursing that might happen.
And then what?
You’re sitting there, in the darkness. It is pitch black. You are likely to be eaten by a grue. On the toilet. What will the obituaries say? And who would think of bringing a torch or a match to the bathroom? It’s not very safe to bring those to a location with a high probability of highly flammable gases.
I guess all one can do is send a tweet about it.
