It's sad to admit but I'm a Dunkin Donuts regular, and considering I order the same thing at least 3 times a week I think I know what my coffee should taste like. The girls who work here are rude. I've only once sent my coffee back because it tasted like water. After telling the girl it didn't taste right she acted like she didn't understand or wasn't willing to make me a new one. So I tell her it tastes watered down, and since she wouldn't make a new one (every other dunkin has always made a new one) I asked her to add more chocolate. She walks over to another employee and so rudely says "it tastes like water!", basically making fun of me to the other girl.
I received my coffee and left only to be unsatisfied for what I paid for. Ever since when I return I always get a nice girl talking through the intercom but once I pull up to the window get treated with a snotty personality. Seems like they might need some male staff or a new manager.
I would suggest trying another Dunkin if you want good coffee and pleasant service.
