I'll go first.
One of my first jobs was at an unspecified fast food franchise founded by a piece of human scum. At this job, in the drive thru window, was a screen. This screen was one that stayed on even overnight, I don't know if I ever saw it shut off. The only thing this screen showed was a leaderboard for drive thru times, filled with us and the other stores in our franchise. They had restaurants within their own franchise competing with each other, and they advertised it to their workers. I don't recall seeing it at another store in a different franchise, so I've often wondered if that's just something that first one did.
