  Like every Dunkin it is hit or miss with if your coffee is just right. These guys more often than not is a hit. At least if you walk in it is. Sometimes drive through it gets missed and also if you doordash and the app gets your order from here sometimes they dont give you the amount of swirl you ordered but again, any and every dunkin is like that. Friendly staff, manager is friendly.

  On January 25, 2026 at approximately 10:25 AM, I had an extremely unprofessional and unacceptable experience at the Dunkin’ Donuts located at 421 Quincy Ave, Braintree, MA 02184 (across from Quirk). This visit is documented in my Dunkin’ app as In-Store Order #226, which can be reviewed along with in-store and drive-through camera footage. I ordered a large iced Dunkalatte and requested to add a protein shot, which is currently advertised by Dunkin’ Donuts as an add-on (there is visible signage stating protein can be added to drinks). I use the Dunkin’ app regularly and have ordered this same customization at multiple Dunkin’ locations without issue. At the drive-through window, a blonde employee immediately became argumentative and insisted they would “just use protein milk” instead of adding protein. I clearly stated I wanted protein added, not substituted. Rather than clarifying or checking policy, she continued arguing with me. To prevent escalation, I went inside the store. Inside, cashier Molly (ID #189847) confirmed I was the drive-through customer. I calmly restated my order. She told me they would need to remove the coffee milk in order to add protein, which is illogical since I was requesting an addition, not a subtraction. I pointed directly to the signage above the counter that clearly states protein can be added to drinks. At that point, the original drive-through employee began arguing with me from behind the supervisor, raising her voice and talking over both me and the supervisor. This resulted in three employees simultaneously confronting one customer, which was intimidating and humiliating, especially in front of other patrons. A supervisor eventually intervened, but instead of de-escalating the situation or correcting the misinformation, she also argued with me and ultimately offered a refund rather than resolving the issue or acknowledging the posted promotion. This location has cameras, and I strongly encourage Dunkin’ management to review the footage from January 25, 2026 at approximately 10:25 AM. The issue here was never the drink—it was poor training, misinformation about advertised options, and aggressive customer interaction. No customer should be raised at, talked over, or belittled for ordering directly from Dunkin’ Donuts’ posted promotions.
