Women might not be aware, but there's a cross cultural, trans-national set of rules regulating how men use bathrooms. I don't know much about Europe, but everywhere from St. Mary's to Maine, the rules are the same, and never spoken. It also holds true in Canada. I can't speak to Mexico, since I've never been there. The rules are as follows:
- Take the furthest urinal from the centre.
- Don't stand next to anyone.
- Don't look at anyone.
- Don't talk to anyone.
- For god's sake, don't even look at anyone!
