I obviously can’t speak for everyone, but this never happened when I was in middle school and high school in the 90s. If someone couldn’t afford the school lunch they had a free lunch program where kids would just go up to the counter and get a sandwich and a juice. No one ever said anything to the kids who got the free lunch because it’s lunch lol everyone’s gotta eat!
Making someone wear a wristband because they couldn’t afford lunch just seems needlessly cruel
