My neighbor contacted a Lawn service company via Craigslist and hired them to manicure his lawn. When the workmen arrived, no one was home at my house or the neighbors, so they fell to and did my lawn instead. I got home and stopped them, but they were so close to done as to make no difference. They called their boss, who had dropped them off and pointed to MY house as the work site, and he came to fix things. His idea of fixing it was to yell at me and demand $250 for the service. Then he yelled at my neighbor and demanded payment. My neighbor refused to pay because his lawn hadn't been done. I refused to pay (but I did offer to negotiate) because I'd never even heard of this company, much less hired them. He would accept full payment and nothing else. The more we talked the more belligerent he became and the less I wanted to be in a conversation with him. So I thanked him very kindly for the free lawn service and went inside. He shouted at my back that he was going to call his lawyer and sue me. How many cards does he have? Who has the legal high ground?
