>> In Guess Culture, you avoid putting a request into words unless you're pretty sure the answer will be yes. Guess Culture depends on a tight net of shared expectations. A key skill is putting out delicate feelers. If you do this with enough subtlety, you won't even have to make the request directly; you'll get an offer. Even then, the offer may be genuine or pro forma; it takes yet more skill and delicacy to discern whether you should accept.
Still, I meant that in the other direction: not request, but a gift/favor. "Guess culture" would be going out of your way to make the gift valuable for the receiver - matching what they need, and not generating extra burden. "Ask culture" would be like doing whatever's easiest that matches the explicit requirements, and throwing it over the fence.
delicate feelers is like octopus arms
