Urinals are many sources of annoyance for me. The automatic ones flush at the wrong time and I don't get why guys throw gum and coins into the drain. Again, people are animals in public bathrooms
There's an unspoken "etiquette" with urinals (and stalls) to leave at least one buffer space between you and others. It's so awkward for someone to invade my space mid-pee at a urinal. Also, some non-curved urinals cause "splashback."
One time at work at a previous workplace I had to put up a passive aggressive sign to remind the guys to quit trashing the urinals. It was an uphill battle and my sign got vandalized. It was have aggravating and half amusing. The problems just got worse when I put up the sign. I soon found urine on the floor, water splashed all over the counters, paper towels on the floor (no effort to get it in the waste basket) I have a whole incident book about slovenly habits from coworkers.
