It’s not weaponized politeness. It’s a love for efficient communication; everyone speaks English, so why not use it.

I’m always like: Dude I’m already in your house, why can’t I just knock on your door.

You can have stalls with gaps under then, that also protect privacy. Like a 15cm gap under the stalls and no gaps around the doors and the chances of accidentally seeing something you shouldn’t are practically zero.

The one I use most is windows+shift+s for the snipping tool!
