Quoted from jar155:This scenario is exactly why I stopped restoring games. I got left with a game a customer refused to pay for. They had me put more into it than it was worth. When I was done, they didn't want to pay and argued they could buy another entire used game for the cost.
This is where I would have had the person pay for the work done and after started on the other work that needed and agreed to be done to the pin. Just my .02 cents.
