If there was an award for worst service, this DD location would win it. Dunkin Donuts in Queen Creek has some of the worst service and employees I've ever experienced. Not once have they ever made the order right. I'm constantly repeating my order over and over, and somehow they continue to screw it up. I only come through around 7 on weekdays, so I can't speak for the later shift, but the employees at this time are very rude.

Pick from:
(a). negative
(b). positive
