    We ordered ahead on the app, a single Caramel Frozen Coffee Chiller, and when we pulled in a couple minutes later it was out almost immediately. Maybe 5 minutes total. They were polite, professional, and quick, and the drink is delicious.

    Every day for the last 6 years, I have visited this location or the 1056 Poquonnock Rd shop. I make it easy on the cashiers by having exact change ready plus a dollar tip. EVERY DAY. Today I asked for a small cup of water for my dog and was told "we don't do that". GUESS WHAT...Never going to Dunkin again anywhere. Apparently my loyalty and goodwill mean nothing.

    I went through the drive thru a little after 9pm. And the employee was struggling with what he has to do at night and to stay open. He was by himself!!!!! That is such a huge safety concern and the load of work he has to do and to manage to try to stay open, is absolutely ridiculous. Do better management. Employee was so polite but I can tell me pulling up stressed him because of all he has to do. Take care of your employees, should never be just 1 person.
