Hostel etiquette

From experience it’s very clear that hostel dorm manners and etiquette are not universal.

Look - I’m not a snob, I know that if things bothered me that much I could get a private room/ a hotel but I feel like keeping your noise level down when others are sleeping, not turning on the big light if it’s night time and others are asleep, turning off your alarms rather than snoozing through all of them, not Leaving all your clothes all over the floor etc should be standard?

Apparently not.

I’ve seen and heard some funny ones so interested to hear more extremes of this behaviour.

Tell me your worst hostel roommate stories. Or occurances that make you think “the AUDACITY”.
