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 fisticuffs because the victim “was being sarcastic.”

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