The coffee was supposed to be flavored with vanilla, but a Dunkin' Donuts worker mistakenly put in caramel. This, of course, led to a pistol-whipping of the worker and battery charges for the aggrieved Florida couple, reports the Miami Herald. Police in Lauderhill say the couple went through the drive-thru but returned to the restaurant upon discovering the mistaken order. During the ensuing argument, police say 27-year-old Jeffrey Wright pulled out a 9mm handgun and repeatedly hit the worker with it as his as his 22-year-old wife, Alexis Longo, got in a few blows of her own, reports the Smoking Gun. Both are in the Broward County jail.
