I once worked with a woman who popped her gum constantly...all day, every day. Asking her to stop would give one a 5-minute reprieve at most. Going to the supervisor would stop her for a day or two, then...POP! It took the entire cube farm going over the supervisor's head to bigger supervisor to get that woman moved to a satellite location. She still popped her gum, but, since she was alone, no one else had to listen to it.
I admit I was written up once for "being distracting" during a meeting. I didn't realize I was flipping my badge and forth, until my supervisor turned and looked at me cross-eyed. Then I fell asleep and started snoring (it was a very long, boring meeting), according to the co-worker who elbowed me awake.
