Dunkin’ Donuts

I’m going to rate this Dunks 3 stars. Most of my experiences have been good here. I frequent this Dunks as it’s the halfway point between my home and work. Most of the workers there are very friendly and know what they are doing.
A few days ago I went in there and there is one girl (heavier set, red head) that was complaining to a «friend» standing at the counter that some customers tend to complain if she does one little thing wrong and one little thing wrong only once!
I had to hold my tongue as this girl has messed up my order 3 times in the past 4 weeks! I am allergic to cheese and two times I walked out of there, drove away, and found there was cheese on my sandwich after I asked her not to put cheese on it. So I had to throw the sandwich out. The other time she left me standing there for about 8 minutes while she forgot about my bagel sitting there and serviced 5 other customers till a customer said to her that I was waiting. She didn’t apologize just handed over the bag and looked at me with her unhappy face.
On top of this she always has a scowl on her face and is always complaining. This one girl is making me want to avoid this Dunks and go to another one. I know it’s probably ridiculous to complain about Dunks but I was once a lower paid retail worker and I always did the best I could to make people have a good experience. It kind of stinks when your ready to eat your food and you have to trash it because «again» the person got it wrong!
