That's not a new rule, that's been around for decades. And it isn't about privacy, it's about minimizing splash back on your neighbor - and only if there are enough open urinals to accommodate leaving a buffer.
If there's a wall of 8 urinals and one guy peeing, you wouldn't go up to the one right next to him to pee.
No, I'm not talking about that. It's always been the rule that if you CAN leave a space between you and the other guys, you do. What I was referring to was some new rule among a certain breed of men that it's
NEVER OK to use a urinal next to one already in use. Not at halftime during a football game, not if there are only two urinals, NEVER. Not under ANY circumstances. Even at the urinals that have the divider walls that many seem to have these days. You're supposed to wait or use a stall.
There have been a few articles on the internet over the past few years explaining this etiquette. A few years ago two guys appeared on some talk show to discuss it. Roseanne Barr was also on the talk show. She listened until she couldn't stand it anymore, then finally blurted out a perfect response. Something like "Some men are such [cats]. Does Mommy still wipe you?"
True, no one HAS to use a urinal, but I'll bet there are plenty of men who wish their homes had one.
When I remodeled my parents' home to put on the market, DH asked the contractor if anyone ever requested a urinal in a house. She replied that she'd installed about half a dozen over the years.
I'd love a urinal in my house, maybe even a trough.
Last night DW and I went to a bar in downtown Orlando, called Sideshow. Lots of freaky decor. The men's room has a stainless steel trough. Three guys could comfortably pee at once, four if you wanted to get cozy. If I had known someone would post photos from a football stadium, I'd have taken a picture.
I really liked the men's room decor at the abandoned, short-lived Hard Rock Park in Myrtle Beach.
