    Recently this dunkin' has declined with their efficiency and I believe it's because of staffing issues. I went there a couple of times, during a weekday in the afternoon and the drive-thru was super backed up and parking lot was full. Went there on Saturday (10/9/26) around 1045/11a and the drive thru was super backed up again and parking lot full. It was expected being that it was a Saturday morning, however the service was slow. The two staff members meant well, but they looked overwhelmed in trying to keep up with the orders. Some customers were asked to pull up and park in order for one of the two staff members to take the rest of their orders to their vehicle. Anyways, hopefully they get more staff members. Owner(s) / corporate pay attention!

    Breakfast sandwiches were terribly prepared. Customers could hear staff yelling at his co-woker. Waited for over half an hour.

    Only 4 cars in line yet I waited over 30 minutes. I ordered one coffee. Thats it. And it was made incorrectly. The guy at the window was super rude. I went to pay with my app which had over five dollars in it and when the guy scanned it, he told me I still owed and that it didn’t work. When I told him that I had a valid gift card and it had worked at other dunkins, he refused to listen to me and just shoved the receipt in my face. He continued to mutter under his breath and was very rude. I told him that the coffee was made incorrectly, and he laughed and walked away. I go to Dunkin almost every day, and this was the worst experience that I’ve ever had.

    MANAGEMENT IS SUPER SKETCHY— DO NOT ORDER ONLINE! The store was not able to fulfill my order due to being out of boxes for coffee, and could not issue a refund in-store. After weeks of reaching out to several different contacts to try and get a refund, I was told they would not be able to refund my purchase, even though I did not receive the product I paid for.
