How characters like their food is supposed to tell us something about them.
Crook: What are you doing here, pighead sucka?
Harry Callahan: Every day for the past ten years, Loretta here's been giving me a large black coffee, except today she gives me a large black coffee and it has sugar in it. A lot of sugar. I just came back to complain. Now you boys put those guns down.
Hot dog vendor: Hey Spock, what do you want on your hot dog?
Leonard Nimoy: Surprise me.Do We Have This One?? Oh, and I'm open to title suggestions. Even before we get deep into the story, (or sometimes afterwards) an early clue as to something about a character would be presented by how they like their food. Popular variations include:
Reckless hardened badass/supposed badass who likes his meat raw.
Someone who is mature and their "maturity" contributes to their ego may like their coffee black, whereas somebody "childish" may want sugar added and/or be taunted as childish for it.
A wacky or irrational character may like a bizarre combination of toppings.
An eccentric and/or bored-with-life character may tell any waiter to "surprise me".Compare Drink Order, which might qualify as a subtrope of this. Not to be confused with Trademark Favourite Food, wherein their preference can be coincidental. There's probably some Truth in Television to this, though it's not necessarily so simple.
