The worst dunkin donuts in the state of Massachusetts. Literally. The worst I have ever been to. I arrive to grab an iced coffee and proceed to get in the line. Line is moving a little slow so I break out my trusty cell phone. Im waiting, waiting, waiting. Nothing. One girl behind the counter moves at the pace of a dead turtle. One younger guy making sandwiches wants nothing to do with customer service so he just buries his head in whatever is in front of him. Other girl that had also been behind the counter, she disappeared out back. Is she still alive? Should I call the cops? Is she ok back there? Who knows. Maybe the donuts got her? I don’t know. Nobody knows. Turtle girl continues her foot dragging, Each customer ahead of me complains about the service. The employees brush it off like its just another day at the concord Street dunkin donuts. After 15 minutes in a line that was no more than 7 people, I get to order. Medium iced coffee with cream only. Turtle girl informs me they are out of cream. Perfect. So as I stood in line for 15 minutes, she felt no need to inform everyone that they were out of cream. Thanks. This place is a dump. Trash overflows the trash cans. Straw bins are empty, napkin holders are empty, bathrooms are disgusting, tables are covered in crumbs. Ive been going there every now and then for over a year since I moved to the neighborhood. I will never go back. I will go out of my way to avoid this dump. Not one employee in there gives any damn about customer service. Not a fraction of an ounce. So long. I hope that girl that disappeared out back is ok. I really do. Your pace was slightly quicker than turtle girls, so you will be greatly missed by the patrons who visit this dunkin donuts.
