food stealing

Hey!!! I want to ask: how easy or hard-to-catch way to steal food from the dining hall for later use if we just swipe 1 time? Like, if I bring a lunch box container and have some rice and other fruits, meat, or veggies on a plate and then transfer it into my lunch box and then, like, hide it in my school bag. Is that ok? Or, like, will someone care about it, especially workers or the manager who is working there, like they would snitch or take any serious action if we steal food?
