Double lock
Because two locks on a flimsy metal gate are definitely stronger than one. This does not really make any sense, is one lock open and the other closed or are they both set up like that on purpose? Perhaps it’s to confuse the thief and buy some more precious moments of time for the authorities to come.
This looks stranger the more you stare at it, for some reason the very sight of this is making us angry. We would imagine that people would break into this gate just to force these people to change the lock. If you walked by this every day, we are sure it would annoy you as well.
