I like that story about the firefighters who were required to wear certain equipment, they knew they didn't need it, so they all wore it, but on their backs instead of their fronts (so it was pointless) but they'd technically done as asked so nothing could be done about it.
I remember working in a restaurant once as a teen, you were ordered to wear badges. One colleague wore two. Everyone else had about 30 of them but we had to buy them ourselves and colleague's argument was that he was wearing badges, as asked of him...
