I'm not sure that you're really replying to my post directly, but:
Yes, agreed. I like Peet's a lot. Though I've never tried McD's coffee (haven't been to a McDonald's since I was a kid). My point is (and was) that Starbucks saturated the market -- almost everywhere -- and recalling what "coffee" was in the US before Starbucks (with the exceptions I already noted), they raised the bar. At least for expectations of what coffee could be. I'd also say that compared to the canned **** like Folgers and Yuban that people used to drink (and I suppose still do), Starbucks was and is far superior.
That said, if you grew up in New York or another big city with Italian (and other) immigrants, you knew what a good coffee could be way before Starbucks. But I don't think you could argue that the majority of Americans had this experience.
This is my point. Though I wouldn't call marketing a science - let alone a high science, if by high science you mean something like the "hard sciences," such as bio., chem, etc. I might be willing to think of it as an "soft" science like sociology, anthropology, or even econ.
