Last year I went to this super modern designer house on a hill side, Porsche painted logo on the floor of the garage, epoxy hallway floors, humongous bathroom, the kitchen the size of my house. He came up to me in the driveway as soon as he saw the lambo diecast in my van his attitude changed, we spoke about cars for a second but I knew instantly he wasn't happy he couldn't look down at me. He told me he was recently retired and he had a law firm, at first he didn't want to sign the contract then he wanted to put his wife business address, no it wasn't happening. Then he wanted to avoid taxes, no!
When I got to the heart of the swap I saw he had ordered the wrong parts and showed him, he asked if I was going to charge another service call next time. Yes sir. (why would I work for free???)
Anyway I called and called to get paid and no answer so I used this nifty new trick and sent him a text message of non payment and I bet he realized it was game over. Nowadays you can't ignore and pretend not to receive text messages and it's valid in court. I got payed a day later and he never called back to swap in the correct parts. I just don't get it, a lot of wealthy people I worked for tried not to pay, complain about the bill and being trouble makers.
