The police had arrived at the fast-food outlet at around 10.45am on Monday after a man wearing a balaclava and holding a handgun robbed the branch.
Mr Benson, who was also celebrating his birthday the same day, described the atmosphere to the Peterborough Telegraph as ‘really tense’.
“It was a memorable day,” he said. “I was driving up to Peterborough feeling a little disappointed that birthdays are a bit flat the older you get.”
According to ITV News, two arrests have been made in connection with the robbery.
