I don't *get* the entitlement culture, I really don't - it comes from being a self employed therapist all these years, believe it or not - far from "blaming the parents" as the cliche has it, my work was about accepting however you felt as a child, and taking responsibility for your life in the present day, and that was the norm in my area. Clients who wanted to bask in blaming their parents for everything either learned differently, or stopped coming along within a few months, because they weren't getting the "poor you" that they wanted. So I think my (non) experience of it is quite niche these days
ETA - feeding, sorry! Erm ... I can imagine people turning down the food that *is* on offer because its not cooked how they want, or an unfamiliar combination. And a lot of disruption - distress/ panic/ fear, all turning to aggression.
