I also have a great amount of sympathy for those of us in this class who are more fundamentally challenged. The ones who seem to suffer from a complete lack of etiquette and common courtesy as well as from peculiar eating disorders. I get it, that home life must have supremely difficult, and the public school system was so lacking that no one taught you how to behave in public, and, specifically, how to eat in public. And how not to.
Food selection: if you are so unable to time manage appropriately, and/or you are utterly incapable of waiting for the break to eat, may I be so bold as to recommend to you what not to bring as your dish of the day?
Tuna sandwiches: they stink up the entire room
Deli sandwiches: see above
Apples, pineapples and other crunchy fruit: your helpless classmates are here to study. We want to hear the professor, not the gnashing of your teeth and the crunch crunch crunch
Chips: Really? I mean, really? Refer to above point about the noise. But to add, you’re dying of hunger, and you choose to stuff your face with a bag of chips? Out of all available food options? It’s not very healthy, you know.
