Teacher was probably fed up with watching children of the entitlement class toss out their “free” lunches paid for with his tax money.
Yup, that’s pretty much what you see in the NYC public school cafeterias. The free or reduced fee lunches are composed largely of frozen pizza, PB&J sandwiches, ham or bologna sandwiches, pasta dishes, wraps with some kind of indescribable junk in them, third-rate miniature fruit (which gets thrown at each other or into garbage cans as basketball practice), overcooked veggies hardly anyone touches, and salads which look like mostly iceberg lettuce. The amount of food which ends up on the floor, left untouched on tables or tossed into the garbage is simply amazing and shameful. What else is appalling and shameful is the extreme rarity (maybe 2 kids in the whole cafeteria?) of kids bringing HOMEMADE lunches.
