I would just like to say a a major hats off to the staff of this dunkin’s! My husband and I were in the lobby ordering as a man and his wife I assume drove up to the window and the employee kindly let them know she was unable to see them and that next time to please wait by the speaker to order. Me and my husband saw the car pull up to the drive through (so they weren’t waiting long before pulling to the window) we then saw the employee talking to them asking what they wanted to order the woman immediately sparks off into a misplaced attitude and then continues to call this employee vulgar language repeatedly before driving away i’m just absolutely ashamed that some woman do not know how to behave I was shocked to see the employee handle it so well and professional if I had been in her shoes I would have lost my marbles!! I truly pity the poor man she has trapped in her clutches (01-29-26 at 8:15pm)

Went at 5pm, was told we weren’t allowed to order food because they’re closing in an hour. Ridiculous, I used to work at a Dunkin, if there’s donuts on the shelves and food in stock behind the counter, you serve it. It’s right there, you’ll throw them away anyways. I’m sure the guy just wanted to take them home for himself at the end of his shift. The drink was fine but his service, attitude, and inability to sell food when they closed in an hour makes this a 2 star review.

Most disgusting iced coffee I have ever received from a Dunkin’ Donuts. Was missing cream and half of the flavor. Before they even handed to me, I told them it looked wrong and asked if they could please fix it. The guy working the drive-through turns around to remake the coffee order and his coworkers cussing up and down at him about how she didn’t make it wrong. I received a modified iced coffee that still tasted absolutely terrible. I tried taking it to a different Dunkin’ Donuts and they couldn’t fix it for me. I am so upset that I wasted points for a free coffee on something that got thrown in the trash horrible workers and terrible drinks.
