You can't tell the man anything. Everything must be done by a professional. For example, when they moved we drove over and helped them with a bunch of stuff, and one thing I noticed that needed to be done was the dryer cord needed to be replaced, so we drove to Lowe's and bought one and replaced it while they were off doing other shit. Well, my mistake was not tossing the cardboard wrapper from the new cord in my car, because once he saw it he hit the roof. "You're not a licensed electrician and I cannot take chances" and blah, blah blah. He's right, I'm not an electrician, but my dad is a Master's Electrician who still holds licenses in 7 states and is pretty highly regarded around the area. I've worked summers and holidays and whenever dad's guys needed the help, so I can hang a light fixture or ceiling fan, replace a breaker and I sure as shit can replace a dryer cord. Nonetheless, once it turned to straight-up BITCHING at us for doing them a favor, we left, and I told my wife I would never volunteer to help him do ANYTHING again.
The next day, he called an electrician to come and have a look at the dryer cord, because "it just CANNOT be right." The electrician told him it was right, but still charged him for 2 hours plus the service call. The highest irony of the whole thing was, the electrician who showed up on the service call was a pupil of my father's in apprentice school.
We were through there a couple of weekends ago, and the wind had taken out a section of their fence...three posts had cracked and it was down. They're currently on a 4 month waiting list for a fence guy. I COULD fix it, but ain't no fucking way I'm volunteering.
