Caller -- hi, I was wondering if you can find a book for me, and if you don't have it could you send it there for me?
Sure, do you have the title and/or author?
Caller -- Yes, it I called Principles of Anesthesia.
Oh, that sounds like a textbook. We don't carry textbooks, but let me look elsewhere. [A minute later I find the book in another system in which we can request].
Ok, so I found it. do you have your card number?
Caller -- Really? Um, no, I don't have my card with me because I didn't think you'd be able to find it so fast! I'll call back later! Thanks.
