I was on financial aid and food stamps as a student. I’d occasionally go to food pantries, too. Doesn’t seem strange at all to me. I worked but my money went towards things like the gap in my aid, insurance, car (lose car = lose jobs = no more college), etc.
Financial aid doesn’t mean you don’t pay anything. Financial aid doesn’t mean everything, including a meal plan, is covered. Financial aid means that you get some help- the level varying based on any number of factors.
