An off duty security guard in Florida went insane on a Dunkin Donuts worker after his coffee order was given to him wrong.

The man ordered his girlfriends coffee with vanilla, but received the coffee with caramel instead.  He then walked into the store to talk to a manager, and ended up fighting with a worker, eventually pistol-whipping him.

Let's recap here . . . He pulled out a gun because he got caramel instead of vanilla.  THE TWO DON'T EVEN TASTE THAT DIFFERENT!

Luckily the police were quick to arrive and arrest the customer and his girlfriend.
