Something that really grinds my gears is that if a bathroom has several stalls, someone ALWAYS tugs on the doors of the occupied ones. Even if you are completely colorblind and can’t see the red “locked” sign, the fact that the door is closed while the others are open should be a hint.
Why do people do that?
They can not open the door because it is locked?
Just to piss you off.
You wanna be glad theres not a hole in the side of the cubicle, you might get a little surprise!! 
I second that opinion.
How are you today?
fine ta, just had the flat cleaned. Not doing alot today - nieghbours round. Ill be back on in a few hours.
Well it’s working! 
Let me have a shite in peace, darnit!
Or people who take the stall right next to you when there are multiple open stalls.
Or as I call them: psychopats
Usually when someone is going to a stall they have to take a $hit and more than likely by the time they get to the stall they already have a “turtle head peaking out”. So they are grabbing at the handles in a sort of mild panic most likey. Read about latchkey incontinence.
Maybe they’re extroverts and they like meeting new people so they’re just trying to be friendly.
A guy here died in the stall, heart attack
Holy sh*t…

Or when guys are standing at the urinal and some jerkass takes another urinal and starts whistling. Ugh! Some people are even bored while taking a piss.
Yeah but if there’s 3 stalls with open doors, why go to the closed one?
Is it the nearest one?
Maybe pissing just makes him happy
That’s nothing, you still have your personal space. Try being a dude peeing in a urinal and some other dude stands at the urinal next to you.
Yep! And particularly the cheap places who don’t bother with privacy panels. I hate going to sports stadiums because of that massive trough. Yuck! Talk about no privacy. You literally stand shoulder to shoulder.
