Without disagreement (or at the least difference of opinion) there would be no need for discussion, and forums such as this would likely not exist. Since chimney sweeps and top hats have already been mentioned here's a slightly off-topic story that some might find mildly amusing. When my wife and I took possession of my parents' house back in 1998 it became necessary to have the chimney inspected to be certain it was structurally sound. The inspector was from a local chimney cleaning service (inspection and a cleaning at the same time) and when he climbed out of the company van he was wearing a top hat. I introduced myself to him, and as we shook hands I mentioned that my best friend owed me a lunch because we made a bet on whether or not the inspector/chimney sweep would be wearing one. He smiled, and without missing a beat said, "If you had hired any one of our competitors you would have lost that bet, 'cause we're the only sweeps in the area who still wear 'em." For the "meet and greet", anyway. When it was time to go to work the top hat went back into the van.
