It's getting harder and harder to break through and get your message seen, heard, or read. This is one of the best ways I know to ensure that people are exposed to your message. I assume you'll need to reach women too, so you'll have to also apply the principle to the backs of stall doors. It may seem silly but it works!
The low-budget version: Get your message on a piece of paper and tape it to the wall. Odeo does it -- why not you?
