Now we know why Ben Affleck was working the window at a Dunkin’ in Massachusetts last month. Besides being a fan of the brand, the actor is starring in their first Super Bowl ad. Dunkin’ teased the ad on socials Monday saying, "Feelin' like we could all use some Dunkin' today," the coffee company captioned an Instagram video. "SOMETHING'S BEN BREWING. 2.12.23." Customers that Ben served during the day he was at the Medford location say he gave them back their money and they got free food and drinks. And yes, Jennifer Lopez is in the commercial briefly.
