Outdated "manners" you'd like to see go away

I should be able to **** with the bathroom door (at home) or stall door (public bathrooms) open.
Many years ago I was at a party. I walked through the people's kitchen and look down the hallway on my way through. There's a guy I'd just met sitting on the crapper drinking a beer with the door wide open haha. Still to this day one of my best friends haha That's not the worst I've seen him do either haha
