After having been to America last year and trying a few places to get a decent coffee, I come to the conclusion that Americans think coffee tastes like something else. All the coffees I tried were so so bad, and in most cases didn't even taste like coffee which I don't even know how that's possible.
I've been reading the Patrick OBrian novels - the master and commander series. At one point the two intrepid English hero's are captives in America. Even they complain most bitterly about the weak, watery substance the Americans call coffee...
I know - been there myself up to Bellevue outside of Seattle in the reasonable comfort of the Hilton. The downstairs staff in the coffee place needed an explanation of what a double espresso was. The rooms had machines with Lavazza pods. Not great, but better than the conference coffee in those huge boilers. (Yuck).
You noticed the Europeans there and the Aussies walking down to the conference sessions with the coffee from their rooms... Without exception.
