As a lurker, I too had to post - especially in response to this.
I was a FSM child in the 80s too. We had to go in for food last as the paying children deserved the “best” food. Sometimes, we just didn’t eat as there wasn’t any food left and as I wasn’t fed at home I could days without eating.
I teach and although it’s all electronic payments through ParentPay, there are stickers on the food that the FSM are allowed to have. My school says it’s to stop kids purchasing crap like chips everyday (stickered food is a baguette, fruit and non flavoured water). I can understand that to some extent but also it still screams “you’re poor”.
