Owner: "I didn't change/touch anything" (said in a straightfaced way by the homeowner who is standing in front of a three gang switch box missing the cover, the ceiling light canopy is dangling 1/2" from the drywall, the three way on the other side of the room is bulgeing a 1/2" out of the wall because the wires behind the switch aren't folded into the box, etc,etc....)
Me: Uhhh....yeah of course not...."so originally the switch didn't work and now the breaker is tripping each time you work the switch?" (maybe because the neutral is now tied to the hots in the ceiling J-Box you idiot?)
Sigh...still I suppose it is just a bit more job security when these goofs pull all the joints apart because of a bad switch and give you an excuse to charge three hours to ring-out all the wireing to figure out how to put it back together right.
