Workers say several people went to the door; they say they got nervous and locked the store. They say one of the men in the group pulled a gun and threatened the employees, "demanding" a sandwich.
The group left the store before police arrived. Witnesses say they had a baby in the car with them.
Police have not made any arrests, but they say the man with the gun could be charged with aggravated assault because he showed a weapon and threatened staff. They say a man with the gun had tattoos on his face and dreadlocks. He was wearing a black shirt with red sleeves.
