The manager of a Dunkin' Donuts in Brockton, Massachusetts, was assaulted by a customer who also shot out the drive-thru window on Thursday.
The incident occurred at the Dunkin' Donuts store at 532 Westgate Drive. Police said the manager tried to intervene in an argument between an employee and a female customer who was in a vehicle at the drive-thru.
Police said the argument stemmed over a sandwich.
The customer then punched the manager and fired two shots from a BB gun, shattering the drive-thru window.
Police said the black Infinity sedan, which had four other passengers, fled the area. Witnesses said they saw the vehicle peel out and make a left turn, initially on the wrong side of the street.
The vehicle has not yet been found.
