Dunkin Donuts locations in Rockland, MA

My boyfriend and I visit this location frequently. I have had issues with customer service in the past but today was the cake topper. I ordered my iced coffee with skim milk and 2 splendas. Then was told at the speaker that "we don't have oreo anymore ". Which earlier in the day...same location. ..my boyfriend had already ordered and received an oreo iced coffee from this same location. So I didn't order anything. I thought it was odd. I pulled up to the window and the young girl at the window says..."I did find one more container of oreo left, do you want the iced coffee? " I said YES PLEASE! ! She hands me the coffee and it looks like chocolate milk...obviously not made with skim milk. So...I say...." that doesn't look like skim milk" she replies "NO!" I give it back to her. I say " I asked for skim milk and 2 splendas". She then hands me the coffee with a ticked off look on her face and I say "thank you " and she replies "yeah". I know how I drink my coffee. I have a condition which does not allow me to drink cream. I shouldn't even be drinking skim milk but I don't like lactaid milk. So I get skim. Without needing to give her my health history or the fact that I spent 8 long years working at Dunkin Donuts. Her service was terrible and there was absolutely no need to throw attitude around as it was their mistake...not mine.
