Hahaha I have a good one for you, a local plumbing/mechanical contractor and a rather large one at that had done a bathroom in a house we recently did an addition on. Well they installed a bathroom fan when it was redone, and and we were labeling her panel which was unmarked and noticed the exhaust fan was not working...... Well the home owner was told it was "super sonic", that it was so quiet you couldn't hear it running. Well needless to say there was no electric to it, no wire, no nothing, they just threw it in and lied to her about it. After we told her she promptly raised hell with them and they did come out and fix it. But that is the kind of work you get when you pay some giant company who hires unskilled people to do thier work for near nothing.
