Be kind to your waiter but treat your barista however the fuck you please because those are in no way in the same caliber of service.
Not at all. Even with 73-person half hours and averaging 3.5 drinks per transaction.
Just be as entitled, impatient, and dehumanizing as you please. Feel free to even encroach on political views and ethnic stereotypes. And be sexist as fuck. The more sexist, the better. Baristas love that shit. They eat it up.
(Fuck you. Fuck you fuck you fUCKYOU.)
