Came by on my way to work and asked for a cup of ice water and the man working drive thru rudely let me know they didn’t sell ice water and they only sold bottles of water. I said ok and asked for a cup of ice and again was spoken to very rudely. I the. Proceeded to ask for a croissant with no cheese. When I got to the window, I asked if it had cheese and she asked the one that took my order and he said it did have cheese. Then another woman came to the window and said if you didn’t want cheese, should have said that. I DID ASK FOR NO CHEESE. I’ve never encountered so many rude people in one restaurant at one time. I have never been more disappointed in an establishment in my whole life.

Went to get a coffee while my car was being serviced at a nearby dealership. The door was locked and there was a line of cars all the way around the building. Extremely annoying that they only do drive-thru at this location seemingly. No signs indicate this and there was nothing on their website. This place sucks.

I had a very disappointing and uncomfortable experience at the Dunkin’ on 5/24 around 3:27pm.
The employee helping me (Kayla) scratched a visible rash on her arm with her bare hands and never washed or sanitized them before continuing to handle orders. That alone is completely unacceptable from a basic hygiene standpoint.
She then asked me when I was due, which was extremely inappropriate and unprofessional. (I was in my car and she couldn’t see me, also it was a 2 minute interaction, she shouldn’t be comfortable enough to ask me about my personal life) I am not pregnant, and no customer should ever be put in a position where that’s assumed or asked.
To make matters worse, her attitude throughout the interaction was dismissive and rude, as if I was an inconvenience simply for asking her to scan my app for rewards.
Between the lack of basic cleanliness and the disrespectful behavior, this was one of the worst customer service experiences I’ve had. Management seriously needs to address both hygiene standards and how customers are treated at this location.

Really frustrating experience at this Dunkin’ on 5/21/26 around 10:30 AM.
My husband went through the drive-thru and made an order. Our order was a breakfast sandwich, hashbrowns, 4 wake up wraps, a coffee, and he tried to get a few donuts but was told they didn’t have the ones we wanted, so he ordered munchkins instead. At the window, he was only given 1 wake up wrap instead of 4 and had to go back through the line to get the rest, with no apology.
Once home, we realized more of the order was wrong. The coffee was made with 3 french vanilla shots, 6 liquid sugar, and 4 cream instead of what was ordered, and it was so overloaded with sugar and additives that it looked curdled and was completely undrinkable. The munchkins were also completely incorrect. We ordered glazed, chocolate, and jelly, but received random flavors including fruit punch and other varieties no one in our house will eat, with no communication or approval for substitutions.
I called the store right away and initially got no answer. When someone did pick up, the employee identified herself as Nellie, though our receipt lists the name Yaneli. She apologized but did not take accountability and said nothing could be done because no manager was there. I could clearly hear a male employee in the background telling her to tell me to go down to the location to fix the issue, even though this is a drive-through only store with no customer access. Not once did they offer to take my name or number to fix the issue.
When I called back at 8 AM today, as instructed, and asked for the manager Megan, the person who answered was extremely rude, refused to take my name or number to follow up, said they didn’t know where Megan was, and then hung up on me.
At this point, we paid for items we did not receive as ordered, the issue was never corrected, and the situation was handled with a lack of honesty and accountability. Between the incorrect order, being misled on the phone, and no effort to resolve it, this was an unacceptable experience.
