An off-duty FDNY EMT was arrested on Saturday after she allegedly threw a mug at an East Village bartender during SantaCon.

Giannella Robalina, 30, was dressed up in a Santa outfit and participating in yesterday's festivities when the incident happened at the Village Pourhouse around 10:15 p.m. According to Pix11, she threw a glass mug at a bartender after they got into a dispute over the bill.

The glass mug cut the bartender's nose; the victim was treated at the scene. Robalina has been charged with second degree assault.

At least one other SantaCon participant was arrested after he allegedly punched another reveler, causing a contusion to the head. Otherwise, there were a lot of people suffering from hangovers today.
