Sliced Bread 2: The Greatest Thing Since Sliced Bread

I was stuck in the elevator for four hours today. No big thing; I had a bottle of water and a book with me. But it's a weak spot in the procedures around here. See, there are only a few people who are cleared to do anything with this elevator, especially when it's on its way to the basement, and they're hard to get hold of. More to the point, they're impossible to get hold of from inside the elevator.

So I had to call Greyghost. Who was, understandably, busy. Which is one of the reasons why it took four hours to get me out of there.

I can report that there are six hundred and sixty-eight little tiles making up the roof of the elevator.
