Actually that's what he did. The woman who had called in the first repair, called him again and blamed him for breaking the machine again: he was the last one to touch it, so it must be his fault. He tried explaining to her how the other part that broken wasn't related to the repair he did and she didn't believe him, especially since it had broken again so soon after his repair. He showed up to fix the machine again and insisted that she stay and see the repair for herself (she was going to leave). He showed her that it was physically impossible for him to have broken the other part as one was only accessible from the top, and the other required him to pull the machine out and lay it on it's back to get to the bottom... but for the sake of good customer service and rep., he wouldn't charge her for the work. After having to do this a number of times for a number of clients who only had Samsungs, he got sick of the constant questioning of his repair skills. It wasn't worth his time and the aggravation.
