I went on a same day emergency service call for a grocery chain we service. The call was for no power to the scale on the meat wrapping machine. They had a scale tech come out and he moved the machine across the room to prove it worked. He then moved the machine back into place and informed the manager to call an electrician since it was not his problem. I get there, walk into the meat room and look at the switches beside the door. The switch marked do not turn off "Meat Scale" was off. Turn switch on and scale works fine. The look on their faces was priceless.
