Reminds me of the time I was repping for a parts company and one shop requested something unusual at the time, a bolt-on steel-rimmed rear cassette wheel. Did not see many of those at the time so I asked to see what was wrong the original and they brought out a wheel with a freewheel body on it. A young guy in the shop had unscrewed the cogs from a freewheel, leaving the freewheel body on the wheel. I said that he just needed to put the cogs back on and use the proper tool to unscrew the freewheel. "Yeah, freehub," was his response. "No, freewheel." We went back and forth like this for a little while. The guy had never seen a threaded hub.
