How often have you come across mindless instructions? This one is not as funny, but still, do you need instructions on how to exit a door? These instructions are pasted everywhere at my work place, probably because we have too many PHDs (permanent head damage) around who don’t know what to do with a door.

Ah, but therein lies the challenge with this particular door. The instructions refer to an exit button, but there are no exit buttons. In case of emergency, the instructions refer to a break-glass. But there is no break-glass either. In fact, what you have is a numeric keypad. I’m sure PHDs will have no trouble figuring this out, so no instructions needed. Exit buttons are just too complicated.
