1. First cubicle
    Ooooh, last person didn't flush. I could flush and use this one, but I'm not going to. Moving on.
  2. Second cubicle
    Toilet seat is down. Too much effort to put it up. Plus, what if I've shut the door, thus committing to this cubicle, and there's something unsavory that's blocking the toilet. I don't need that kind of surprise. Moving on.
  3. Third cubicle
    No paper. No good. Next.
  4. Fourth cubicle
    Seat is up. Bowl is clear. There is paper. We have a winner.
