At the drive-through, she makes a scene... and ends up drenched in iced coffee

Things get out of hand at a Dunkin' drive-thru in the United States: a furious customer yells for a refund through the window. The employee, clearly at his wit's end, ends up throwing an iced coffee right in her face. The drink splashes everywhere; the customer screams and steps back, even losing a flip-flop in the process. The whole thing was caught on video and is going viral on social media.
