Dunkin’ Donuts? While most of the city was under lockdown early Friday because of a manhunt for the surviving marathon bomber, apparently some of the Dunkin’ Donuts were open. With hundreds of cops patrolling the city of Watertown, everything was closed, aside from four donut shops. A store manager explained it: “There was an automated message going around telling businesses to close, but because we’re Dunkin’ Donuts, we called the police department and they said we didn’t have to [close].” BuzzFeed confirms—some locations were told to remain open to help cops and first responders. And yes, everything was free.
