I've long been very annoyed by English speakers who claim that something "works fine" or "runs fine".
To me, it sounds like they are saying that it "functions OK, if you have very low demands and high tolerance for flaws/glitches". "Fine", to me, is a word that is either rarely used correctly, or actually doesn't even mean what they seem to think it means from the beginning.
https://www.dictionary.com/browse/fine seems to suggest that "fine" means "perfectly", but that's not my perception of the word.
Isn't it at best highly ambiguous if you want to say that something works exactly as intended and you say that it "works fine"? Wouldn't you say "works perfectly" or "works flawlessly"?
"Fine", to me, sounds fundamentally like a "compromise" of some sort.
