I bought an extra large coffee at Dunkin Donuts today. After I drank it, I decided for certain that it was way too big, and contained way too much caffeine.
Large coffees are usually not a big deal for me, but going up to the extra large size had an impact. I usually stick with small coffees from Dunkies too - they are paper cups, and I like the paper cups better than the Styrofoam cups.
I had previously wondered why they don't have extra large iced coffees. The size of the extra large hot coffee, plus all that ice, would be huge!
Note to self - don't get an extra large coffee next time!
