I once made that exact threat in my food service days, but it was to protect me from my manager. I was the assistant manager of the store, and for some reason my boss decided that she was going to pit the new employee against me. So she would tell the new employee I was talking bad about her, then get on me for things I allegedly said to/about her. It was obvious to me because the things she was claiming I said were things I'd never tell an employee. I finally got tired of it and said "Okay, if you're going to keep accusing me of saying things that I'm not, I'm going to buy a bodycam and will gladly let you show me where this is allegedly happening in my footage." After that, all of the accusations stopped. The new employee realized that we were being played, and we ended up being pretty good friends.
