Ben Affleck and Jennifer Lopez surprise customers at a Dunkin' drive-thru in Massachusetts.
Affleck served coffee dressed as an employee, with a headset and all.
"Incredibly funny and quick-witted," according to customer Lisa Mackay.
A film crew was present at the location, and Mackay signed a form for video use by the company.
Mackay posted a photo of Affleck serving her on Instagram and thanked both Affleck and Lopez.
Another photo on social media shows Lopez standing alongside Affleck.
Dunkin' company tweeted a hilarious looky-loo eye emoji in response.
Affleck is a known Dunkin' enthusiast and has been photographed with a cup multiple times.
Affleck is excited about Dunkin' opening locations in Los Angeles in 2019.
