Is this guy a regular, it doesn't sound that way, sounds like a homeowner who was pissed that the wife made I'm get rid of something. Why bring something in and not get paid for it? Sounds like its a customer you don't want around anyway. Make all the changes you have to make, get some good coverage of it thru local media, and move on. It unlikely you or any other yard will see this guy again. I think you and your staff went above and beyond to make him happy. Good job!!!!!
