I was always viewed as a fussy eater as a young child. Both at home and at school, I drove people mad with my preferences and the volume of foods which I just refused to eat.
Schools tried different approaches to this but were generally unsympathetic. I remember having to take my plate to teachers eating on a stage at the end of the dining hall to ask permission every time I wanted to leave something uneaten. Given that there was no choice in what we were served, this happened a lot, and I was admonished for my near daily requests.
