I’m not doubtful about that either. I’ve seen a few posts over the years of some pretty sad looking lunches, and I seem to recall something about trying to pass off pizza as a vegetable, so I’m sure there’s been shenanigans and corner cutting.
At the same time, I hear friends talk about all the extra supplies kids need to bring these days, and my brother was complaining this week his kids needs dedicated gym shoes to leave at school, so they didn’t seem to be detected from passing along costs to parents anywhere else.
