Dunkin Donuts locations in Hickory, NC

First I would like to say I have visited this store many times and have had no complaints; workers are friendly and food is good. However, I stopped this morning on the way to work and spent 15 minutes in the drive through line when there was only 3 cars ahead of me and then I received a terrible cup of iced coffee. Again, I am grateful Dunkin came to our side of town but the residents on Springs road are truly hard workers and don't like being late for work, nor do they like bad coffee. Please add some workers to the drive through line in the morning and let corporate know the pre-bagged iced coffee needs some help. Other than that please keep up the good work, we want you to be here for some time to come.
