I have wondered ...
Supposedly, the lock in a dorm door is to protect the guests staying in that room from other people. But actually, with new people arriving every day, and people leaving every day, most of them strangers to each other (and more so in dorms with many beds), does it make sense to put a lock on the dorm door when most people in the room are strangers to each other?
Does it make sense to put a lock to prevent "strangers" from entering the room, when most inside are probably strangers to each other?
If there is a thief amongst those strangers in a dorm, a lock on the door, won't prevent theft from happening. Some would say, if theft occurs, we can reduce the number of suspects to those staying at the dorm. But even so, who do we accuse? Those staying at the dorm? Also those who just left the dorm and hostel? Also those who just arrived at the dorm? Every day, there might be new people entering and leaving.
I am still toying with the idea of not having locks at the dorm doors. Is it a real necessity or do we do it just out of habit?
