Reminds me of a problem we had at work years ago. The computer (a
DEC VAX) rebooted every night, we could not work out why. Turns out the
cleaner's large backside hit the reset button when she bent over to
change the nozzle on her vacuum-cleaner. Every night!

Cleaners are a menace around electrics.


Ever seen nurses thumping in crooked plugs in a hospital.
