The "keep your eyes out for cues" works the other way around in what we're calling a "Guess culture" as well.

That is, most natives of such a culture will be providing you with hints about what you can do to help them, while at the same time saying "Oh, it's all right, don't inconvenience yourself on my account." Paying attention to those hints and creating opportunities for them to provide such hints is sometimes useful.

(I frequently observe that "Guess culture" is a very Ask-culture way of describing Hint culture.)
