Demand or request?

I absolutely dislike it when patrons come in or call and tell me how I should search for their information. I have probably mentioned this before.

I had a call today from a patron who started off with: "I want you to go to the Red Book and....." I could feel my blood pressure going up. He continued, I'll narrow down to the years 2000 and 2001 for you so you know which book you need to look at.

Really! Why thank you! What would I do and where would I be without those friendly!! instructions.

Just ask a question and if I need further information I'll ask you. Deal?
