One job I had at Disney involved waiting for long stretches for a specific thing to happen. When that thing happened, we were busy. In the meantime it got quite boring. One of my coworkers was a very even-keeled, diplomatic sort. One day I got bored enough that, in an effort to entertain myself, I started walking laps of him, just to see how many times I could circumnavigate the poor guy before he said something.
He never said anything. After 12 laps, he just walked away, and never mentioned it.
