Sort of like pulling and signing off a building permit here. The local city planning department makes people jump thru tons of hurdles. Then when the project is done the building inspectors nit pick trying to find something they can tag you with. After building a 1500 square foot addition to my last house, I left the airator off the garbage disposal on purpose, the inspector tried to nail me with improper ceiling fan vent in the bathroom, because it didn't have a built in night light. He was grinning while telling me I'd have to replace it as it wasn't to code. I smiled back and asked when the code had changed, he said 6 months ago, I then pointed out I had pulled the permit 4 years ago and it was up to cade at that time then he got mad, so he goes to the kitchen sink and points out I don't have an airator venting it on the counter top, I just smiled again, reached under the counter, pushed it up thru the hole and said oh you mean this, it must of fallen down and screwed it back in place. He wasn't happy but he did sign it off!
