Don't go into the shop unprepared. Strike an arc with confidence knowing that coffee (I mean, no one really knows what's in that mug) is always within reach. It's available in two sizes: 11 oz for mortals, and 15 oz for those among us that prefer to imbibe coffee from a cup that is sized “more in the nature of a bathtub," just like TR would have.
