About 10 years back I helped some friends close up their engraving shop. I had helped them with their shop for well over twenty years before that. One of the really neat things they had was a 100W laser system the used every day. It had a controller computer and every font and image conversion software ever needed. They had two of these lasers, and were going to take one with them to do "neat stuff" in their retirement home in GA. They has spent the past five years building what could only be called a Chalet in the hills south of Atlanta. We loaded theirs in a shipping container of things that they were taking to GA. (I was to handle the pick up of the container for them after they were gone.) I offered to buy the other one. They told me I could have the other one as well as the computer and all the spare parts and consumables as a thank you for helping them for so many years, and for all the work packing, getting the building ready for sale, and handling the shipping. We put my laser and all the rest in the back room, which was already filled with tools and stuff they had given me. When I came on the last day to load it all in a rental truck ( yes, there was that much stuff), the parts and consumables were there but the laser was gone. I asked them where the laser was and they said it was with my stuff in back as far as they knew. After some panic, we found out that their son-in-law had "loaded it by accident" late the night before when he was loading his truck with stuff he was going to sell on ebay. They were more than a bit embarrassed, so I just said, "No big deal. He might as well take all the parts, too." They said, "NO, we wanted you to have it.", and called him up to bring it back. He said he was too busy to bring it back that day, so I offered to pick it up the next morning at his place. When I came by to get the laser, he told me he had already sold it for $1000 to a local engraving shop. He had the cojones to ask me to give him the other stuff so he could sell it to the buyers, too. I said "No", and went back and packed it all in his folks shipping container. I didn't say anything to my friends, and saw them off to Atlanta a few days later. I heard that they were so pi$$ed at him when the items arrived in their container that they told him he was not welcome in their new home for the big family Christmas that was going to be house party/family reunion. His wife was so mad at him that she went without him.
