Or have we gone one step beyond bonkers?

Most Saturdays I go for piano lessons for an opportunity to try something new and believe me I will never, ever be a concert pianist!!!

So today on my way to my lessons I happened to stop at a supermarket to use the toilets. Inside the gents toilet which has only one door into a small toilet with no other exit, I happened upon the sign on the back of the toilet door

Now I might be missing something here but ina room with only one entrance door, which doubles as an exit door, should we really need to let people know how to exit the toilet? I started looking for signs to remind you to breathe in and breathe out!!!! but then that would be stoopid wouldn’t it
