Starbucks is an essentially American phenomenon. e.g., nobody in Europe ever thought coffee shops needed to become branded chains that set a single product quality expectation, because almost nobody who'd ever visited an Italian/mediterranean-style cafe ever thought they lacked a quality or sociability option to begin with. Sure, some chains exist, but the quality delta between them and the average cafe isn't great enough to scale fast.

Only in a place where coffee is generally awful, and VC money easy, could the concept that became Starbucks ever come into existence.
