I'd still get down with a govt cheese grilled cheese sandwich.
When I was in elementary school, the cafeteria didn't take cash. I guess it was an effort to keep kids from having to carry lunch money every day. If your kid was going to eat from the cafeteria, you had to buy "meal tickets". These were punch cards you'd hand the cashier, and she'd punch a hole in a square and hand them back to your teacher. I remember there were different colors for different value cards. The blue ones were the smallest denomination, and the white ones were the most expensive/longest lasting. The kids like me on free lunch got these big orange laminated cards that said FREE in big block letters. The teachers kept track of all the cards, and before lunch every day they would walk around and hand out the meal tickets, and you had to carry them in your hand so the teacher could see them as you walked single file to the cafeteria. Even at an early age I was embarrassed as fuck having to carry the big orange "I'm poor" card.
