Roommate gets mad when someone shits

3 people, 1 bathroom. when you gotta go you gotta go. anyone think it’s okay/necessary to flip out about them needing to shit? is is okay to make a big deal over how it smells? anyone have a roommate where they feel like they need to ask permission to shit?

i would wake up and need to use the washroom. they will get up right after to use the washroom. they would see the bathroom door closed (to not spread the stink) and storm back into their room and complain that they’ve had to pee for a while, and now they can’t use the washroom because i shit.

edit : yes i spray febreeze, open the window, and turn the fan on. and only one roommate can smell it apparently. i have tried everything; incense, matches, febreeze, candles. i have not done the courtesy flush because i can’t waste water lol

how would you handle this?
