That librarian over there was talking down to me

That's what a patron yelled when he walked away from me. And, my co-worker said, "You do talk down to people, we(meaning him) are surprised that you haven't gotten slapped." I said, "I don't think I talk down to patrons." My co-worker did admit that in this instance, I was not in the wrong.

The patron approached me at the desk and said, " I would like a bibliography of Johnny Appleseed." Now, somehow, I knew that he meant biography. I conducted a keyword search and found that we only had one adult biography in the system, it was unavailable, but there were plenty in the children's room.

I said to the patron, "The is one biography, but it isn't available, you'll have to place a hold on it. It was checked-in today, at a branch, and it is in the process of being returned here."

The patron then said, " I want something that I can check-out today."

I said, "Well, the adult biography is unavailable, but there are a lot in the children's room."

The patron walked away and returned with a call number for the book that I had just told him about, but he said, " I want a bibliography on Johnny Appleseed and here is the call number for what I'm looking for."

I said, "That is the call number for the book I just looked up, and it is a biography. That title is unavailable, but there are plenty in the children's room."

The patron repeated himself, so I repeated myself slowly, so that he would be able to hear every word that I was saying.

The patron repeated what I said and walked away. Once he got over to the online catalogs, he began yelling, "THAT LIBRARIAN OVER THERE IS TALKING DOWN TO ME!!!
WHY DO ALL OF THESE BOOKS ABOUT JOHNNY APPLESEED SAY jB. I CAN'T FIND THE AREA WHERE THE BOOKS ARE. HE WAS A REAL PERSON AND I WANT A BOOK THAT TALKS ABOUT HIS LIFE."
I just let him talk, because he obviously didn't want my help. My co-worker finally said, "Let me go over and help him because he isn't understanding what he is doing."
