A man walked into the corner store with a gun, planning to rob it. He demanded all the money in the till. The cashier put the money into a bag, as the robber instructed him to. The robber then demanded the bottle of Scotch he saw behind the counter. But the cashier wouldn't give it to him because he said he didn't believe the robber was over 21. The robber pulled out his driver's license to prove it and the cashier gave him the Scotch.
After the robber left, the cashier called the police with the man's name and address. He was arrested soon after.
