What would you say if I sprinkled antifungal powder all over the locker room?
Is there a reason you'd spread it all over the locker room?
Just to annoy everybody who uses the locker room.
It's not okay to make such a mess in a communal area. Somebody else is going to have to clean all of that up. Leave the locker room as clean or cleaner than you found it.
But they don't deserve it.
Even if the other people in the locker room annoy you, they don't deserve to clean up a mess you left in a common area. Just go about your business and try to ignore them.
