- There's a big red button in a glass box in some room somewhere that [cuts all power to the building in case of fire]. Somebody took a visitor near that box. The visitor mistook the button for the button to unlock the door release...
(The button is now labelled.)
The mere act of looking at this button when there is no danger of fire will summon a large flock of leather skinned winged hell demons with extremely bad breath from the darkest recesses of oblivion to dine on your pancreas in the middle of the night. Thank you, The Management.
xinit pointed out to me that humans don't read. Period. Well, we could just translate that into Latin to make it into a Protection Spell on the button.
