Urinal rules: 11. Given a string of unoccupied urinals, you must choose one on the outside. When one outside urinal is occupied, use the other side, then middle. Avoid standing directly next to somebody at all costs. For example, given seven urinals, here are acceptable configurations: X...... (X == occupied, . == empty) X.....X X..X..X X.X.X.X XXX.X.X <-- These are only acceptable when significant XXX.XXX <-- "privacy" dividers are available. If the XXXXXXX <-- urinals aren't divided, use a toilet. 12. Always look at the wall. Looking down means you're obsessed or don't know what you're doing. Looking at other people is threatening. 13. Flushing is optional. Over time, the water will become a rich orange. At this point, flushing is mandatory. 14. Don't start unzipping until you're protected by the privacy of the urinal. Don't step back until you've closed your pants again.
