Rule 72. When you’re in the library, obey the noise rules. Disobey the food rules.

 

Nothing is more annoying than a people talking loudly in the library, when you’re in the library respect the people around you and the sanctity of the place you are in.

But bring a sandwich because you might get hungry, if they tell you you cant have one, put it in your backpack and eat it later when they leave. Unless of course you are around some expensive books, then, save the sandwich for later.
