Had a guy pick up a kitchen, from the house we are going to eventually demolish, that I advertised on Facebook. Found out during the week that he dumped a lot of renovation rubbish in the backyard, hidden behind the garage, when he picked up the kitchen. Funnily enough it is all on CCTV. He also underpaid for some other items he purchased out of the house, and took a fire grate as well. Been talking to the police and council about it and something will be done if he doesn't get back to me and remove it over the weekend. I really hope he doesn't.
I had an Irish uncle who said, "The only person you can trust is the one wearing your pants." Now, discounting the possibility that someone has stolen or borrowed your pants, I get where he was coming from. It's sad that we expect others to live up to a reasonable code of conduct and frequently they don't.
