I have a love hate relationship with this Dunkin location. It's like a 50/50 shot on if they'll get your order right. Somedays, everything is perfect, comes out hot, fast, everything you want from Dunkin'. Then there's other times, like this morning where whatever you ordered goes right out the window. Now, I would give slack if it was rush hour M-F, but not 10:30am on a Saturday when you're the only car. Our iced coffees definitely have some added flavoring (vanilla maybe) but no sugar, and our breakfast sandwiches were both lacking cheese (and mine was on a crissoant not bagel).
My suggestion...ALWAYS check your order before you leave, or there's a good chance you'll be VERY disappointed.
