Punching a customer because he’s being sarcastic? Yeah, right!

An employee at a Radio Shack in Parsippany, New Jersey was arrested last week after he punched a customer for being sarcastic.

When cops were summoned to the store, they found the customer “holding a bloody paper towel to his left eye.”

The employee, Andre Santiago, 20, hightailed it into the back of the store where he told officers he elected to use fist-a-cuffs because the victim “was being sarcastic.”

There’s no word whether authorities insisted Santiago give his zip code while booking him.
