Miss Information is annoyed by passive aggressive regularsMiss Information likes it when people get directly to whatever stupid point they're trying to make. It saves a lot of time and energy. Besides, it usually means that she can do whatever you want her to do and return quickly to her preferred method of whiling away the work hours--you know, not having idiotic conversations with the customers.
Anyway, Guy-With-The-Eighties-Hair, you are here every damn day. You know how things work. You think those high school kids are making too much noise? Excellent. Miss Information is always willing to embarrass high school boys in front of their friends. (She does have some unresolved issues...) All you have to do is ask.
Instead of that you come to the desk and ask if this is "still a quiet study area". Listen up, pal, Miss Information is the sarcastic one in this relationship. You are a mere amateur in comparison. In addition, you must understand that phrasing the question that way makes her want to invite a mariachi band to perform live at the Reference Desk just to annoy you.
