The stupid café down the street fucked up my order. I asked them for a flat white and they gave me a latte.
The place is amazingly cheap so I'm normally inclined to overlook mistakes, but giving me a latte instead of a flat white is not a mistake I can overlook because I am lactose intolerant and a latte has, at a guess, about six times as much milk as a flat white.
At least this place understood the meaning of "decaf." Given my brain's hostility to the idea of sleeping regularly every night, consuming any amount of caffeine would be a Very Bad Idea®.
