So when you go to work, and it might or might not be before you've had your coffee, and you go to turn on the light switch, only to find that with one simple motion of turning the light on, you blow the circuit.  The office is dark, and you and your co-workers spend the next 30 minutes trying to find the right breaker until a maintenance guy comes in to help and solves the problem.  Thankfully electricity is back on and hardworking people can get to their hard work.  And when your co-workers tell you that you should NEVER flip those switches because they haven't worked FOR YEARS, and you suggest that they put a sign, so unsuspecting new-ish people have a clue, they oblige and make this sign.  That was the start to my day.  Thanks my marketing lovelies.  You make me feel special.
