It sounds like you do see it in real life as much as online -- but suspect that there may be a selection effect going on that is causing you to see a disproportionate amount. For myself I mostly see this sort of entitlement online, but also think that's related to a selection effect (I've been online a lot over the years, and I deliberately choose real life situations that are less likely to have such things happen). So I'm curious about how much of that is selection effect and how much is a genuine difference.

I'd guess that the underlying cause is similar in both cases (not seeing the other person as a individual with their own needs, goals, etc). But that can probably manifest in lots of ways. It may just be that "online" is one of the few situations that "people with privilege" see it happening (ie, without markers that you're a Very Important Person you might get treated just like anyone else, or witness others being treated that way). Which is, itself, a measurement effect.
