Don’t touch another man in a public restroom. It doesn’t even have to be said.

The men’s room at the Dubliner in Tampa ranks low on the square-footage scale. Think of a box with half of it walled off into a stall. A urinal and a sink snug themselves into the other half. When I walk in, both facilities are occupied. I pause near the sink.

The man at the urinal finishes. He turns around, and I attempt to edge around him. As I pass, he taps me on the elbow.

“All yours bud,” he says, before pulling the door open and leaving without washing his hands.

Okay. Backup. Let’s review the facts. He has his back to me. I have no idea which hand he uses to handle his affairs. He finishes, and touches me on my elbow.

I proceed to my aim, thankful for the long sleeves on my shirt. Man Rule: Never make physical contact with another man in the bathroom.
