'He just looks at me dumbfounded: "Wait, you mean I have to pay for this?"': Locksmith enacts extremely satisfying revenge on irritating customer

His business also had a policy that protected his power move, which left the customer in an even worse spot than they'd started in. Up next, read about these Redditors who shared their favorite examples of new rules that immediately backfired, with hilarious results.
