What have you eaten in the university cafeteria?
I remember that the most I ate in college was hair, and then I drugged my food? It's just that kind of flies, and some things are still disgusting. It's disgusting to think about it now, but I won't eat it when I see it. Sometimes they will talk about these problems on the advertisement wall, and then maybe the merchants will pay attention. If they see it, I think it's better. If they can't see it, I think food hygiene should be improved whether they see it or not.
