It's happened more than once – cafeteria workers taking school lunches away from children who don't have enough money on their pre-paid accounts and throwing the food away right in front of the child.
In one instance, school staff even stamped kids' hands to mark them out.
Noelle Roni is a former principal from Colorado who was fired in November, she says, for standing up to this policy and demanding cafeteria workers stop the stamping.
Roni spoke to CNN's Chris Cuomo on "New Day" Thursday and said she believed she was punished because a lunch staffer quit after she spoke with that person. Roni defended herself on the show.
"I had big concerns about kids not eating and we got to work together to get kids to eat in order to learn. I'm a very hands on principal. I was in the lunchroom every day, I saw what was going on. I had great relationships with the kids, and so I spoke directly with kids and families about this."
