Urinals

 

There are two rules you don't break:

1. NEVER stand next to a someone using a urinal to use the adjacent one (unless you are part of a line of three or more people waiting to have an open one). Meaning there should always be a pattern of used-unused-used-unused unless in at a place like an airport or stadium, and lots of people are there. And

2. NEVER talk to the person next to you while using the urinal. Never.
