Yup, the unspoken gentleman's agreement of the urinals. Don't ever take the urinal directly beside someone else. You take the one farthest away, and if you have no choice, it's still preferable to just pee in the stall. Pooners will never understand this though, since they're not men and they never will be.
Just as an aside, it reminds me a lot of the radical feminist who legitimately believed that men have secret meetings in the men's room at work, since that's the only place they can be away from their female coworkers. She had millions of men in the comments inform her that, no, men do not have secret gatherings in the bathroom like women do. Another unspoken rule of the men's room is you do not talk to anybody, especially when they are in the process of taking a leak/dump. Men don't talk to each other in the men's room. We go in, quickly do our business, and leave. It's why I laugh so hard at the pooners having anxiety attacks over using the men's bathroom. They just don't understand that men do not give a shit. Just go in, relieve yourself, and leave. It's not a social meet, it's not the cool kids club, it's the bathroom. Piss or get off the pot.
