Should you be able to drink and eat anything you like in the library? (Yes/No, explain why)
No. Because it is a library not a cafeteria or a restuarant, there are books all over the place and this particular library has valuable books not found anywhere else. I'd rather it stayed respected and clean.

Is the library supposed to be a center for drama or learning? (pick one of them, explain why)
Center of learning, of course. It's the original purpose of a library and Drama happens almost everywhere else any way, might as well keep one place drama-free.
