Congratulations, Ben Smith, staff writer for the Atlanta Journal-Constitution:

Note to robbers: don’t take a knife to a step ladder fight. That’s what one thief discovered when a customer at an Acworth convenience store on North Main Street bonked him with a ladder used for reaching items on the top shelf.

The robber had just threatened to cut the Quik Thrift store clerk’s neck if he didn’t give him cash, authorities said. The clerk complied.

Then the customer — a regular who is known to store workers as “Caveman” — grabbed the step ladder and smacked the suspect at least once. The robber dropped some of the money and fled.

The customer with the step ladder chased him out of the store.

You win the Matt Duffy Great Lede contest.
