When the lock on the public stalls doesn’t work
This is probably one of the most awkward situations ever. When you are lucky enough to find a public bathroom when you really need it, there is a catch- the lock is not functioning. You could either risk embarrassing yourself by peeing your pants or someone walking in when you are in the stall.
Or, you can just use a regular rubber band and wrap it around the lock to fasten it closed while you are in there and do your business comfortably without risking anything! TikTok sure comes in handy sometimes!
