In latin america we say "Mi negro, mi flaco, mi gordo, mi pelado" ("My black, my skinny, my fatty, my baldie") and could not care less. Sometimes even to strangers.
Believe it or not, I've met two white people, both from the Southern U.S., who would look around and whisper the word "black" when they used it. When talking about black people, but also in other contexts.
This is dumb, like really really dumb. So dumb it's unrecognizable from conservative propaganda about how the libs are too triggered to even order black coffee.
In your area, that may be true. Around here, and by experience in a good chunk of southern Europe, asking for a coffee will get you an espresso 100% of the time.
Asking for drip coffee will probably get you scorned and sent off, or if they're nice they may offer to make you instant coffee if they have it.
In Spain we don’t ask for café negro (but reading the comments now I learned that in other spanish speaking countries do), we just ask for coffee (anything else is a modificator) or to remark that we just coffee without anything else we ask for a solo.
But I cannot speak for the whole country, it varies a lot from region to region the names for ordering coffee, maybe in some parts do in fact say café negro.
We call that "an American" coffee in Mexico, as in un café americano or un americano. It used to trip me up because I expected café negro. Odd regionalisms, I guess.
Americano is usually espresso watered down most everywhere, no? I guess I just assume it’s not what Americans generically call “black coffee” which is drip coffee. If I ordered Americano most places outside the US I’d expect the espresso version, not drip.
A regular coffee is 1 cream and 1 sugar, so the sentence in the first panel is a command. He's even pointing at the guy while he says it. The nasty racist then backtracks when he notices the barrista's cold dead stare and realizes he is large enough to snap him in half.
I'm just joking around, but really the more I think about that first panel, the more it annoys me.
edit: I wasn't seriously considering this a racist comic, but pointing out a widely used label and grammar will make the first panel hilariously ironic to many people.
Now go look in that box of Crayola for the one that's gonna trigger the SJWs to fight against a language because some hillbillies used a word as a slur and now live rent-free in everyone's heads.
