Today 11/20/2023 at approximately 3:10pm was the worst customer service I have ever experienced at a Dunkin' Donuts in my life. The person I dealt with today was extremely rude and impolite. And the worst place, honestly. I asked him to warm up my bagel twist because it was cold. He started screaming on his own insolently. He told me the water is not free. I told him I asked you to warm up my bagel twist because it was cold. I didn't ask you for free water. I have my money . He said to me, "I don't understand what you want." I told him that if you do not understand, you should speak gently. He started speaking rudely. Worst customer service.
