Really, how does someone even begin to think that this installation is remotely okay. Because this is so blatant, I would think this person bids low and only is concerned with the bottom line. I would also bet this person is the first to cry fowl when he has some poor job thrown his way. This is idiotic and gives our industry a black eye.
The question begs - as a legimate contractor do you tell the customer this needs to be fixed?
