This is one that I get often at work.
Idiot: I got a call from you. What do want.
Me: Do you have a student loan?
Idiot: Yes, what are you calling about?
Me: I will need to look up your acct first, may I have your SSN?
Idiot: I am not going to give you that!
Me: I might be able to look it up by your name, what is your name?
Idiot: I am not going to give you that information until you tell me what the call was about.
Me: I cannot tell what the call was about without accessing your acct.
