In all fairness the father Marisa also talked it up as this wonderful, amazing food. I don't blame the older sister Reimu for wanting to eat some as well, and being upset when she was told 'no'. It's one of those things that seems like inequitable treatment from the perspective of the child, and only makes sense when you're an adult.
Everything that comes afterward though, is without excuse and this Reimu proves to be a total shit.
