I suppose you could call it a kind of metonymy maybe Veteran? Or just elision, where "have you eaten a meal recently" is shortened to "have you eaten?" and the rest is taken as read by both parties, because there'd be no real reason to be asking whether you'd eaten a snack this morning when it's now past lunchtime.
I struggle with the frequency words when filling out Likert forms for mental health related stuff. Like, say it's a form about depression, and the question is "I think about killing myself: never, occasionally, sometimes, frequently, all the time". I might be at my very lowest, ruminating on my impending suicide any time I have a chance, thinking about how, and when, and why I should, and so on, it's my main preoccupation and my mind can turn almost anything into another reason to think about it, but I couldn't in all conscience tick "all the time" because firstly, I sleep several hours of each day, and secondly, even the supreme Buddhist masters can't successfully focus on a single concept for every waking second. Sometimes your mind drifts to how much your legs hurt or how much of a failure you are or how filthy your house has got. I think they didn't test these things on linguistically-pedantic spergy people.
