Frappuccinos are associated with children and fatties, at least according to the baristas. If you're an asshole, expect the barista to give you decaf or the wrong steamed milk.
I guess that's it? Starbucks is just overpriced heavily commercialized bullshit imo. When I worked at a travel plaza, I would always drink their teavana tea. I would get it for free; there's ni way I'd have ever paid for it.
