You'd get mad if someone spilled coffee on your laptop, right? Mad enough to toss tables, chairs, and PEOPLE? You won't believe this incredible video! The prank is pulled off flawlessly, and the customer's reactions are priceless. The video belongs to Youtube User 'CarrieNYC' so I'd be willing to bet this incredible prank is a publicity stunt for the Carrie reboot hitting theaters October 18.
