Why did my day have to end like that

Mr. TIGER BAL.M himself chose to approach me at the reference desk. He mumbles and I couldn't understand half of what he was asking. I told him to write down whatever it was that he was looking for. He admitted that he should have asked for it downstairs, because it's probably fiction.

I finally found the book that he was looking, translated into English and it is fiction. Fiction is on the first floor, where he came from. I told him this and he argued with me about why there was probably a copy on the 3rd Floor. I finally stopped him in the middle of his rant and said, "I can't understand half of what you are saying, so quit talking to me and go look for your book!"

He then asked me what the largest country is in Africa, I told him I didn't know. He then said, "Why not, haven't you been there?" I told him no. He then asked me, "Why not?" I said, "Why haven't you been there, you're the one with all of the questions?" He then said, "Oh, you haven't been there because of money. I haven't been anywhere."

He then starts with me about the dictionaries. He asked me where the dictionaries are. I began telling him where they were and he yelled, "OH YEAH, YEAH, I KNOW!" I said, "If you know everything, why are you asking me?" Once again, he started up, talking about the size of dictionary he wanted. I told him that he better leave me alone, because I was done talking to him because he wasn't speaking clearly anyway.

When he finally left, my co-worker said, "He always has to be correct, even if he's wrong and you show him the answer written in black and white. Then he has to have the last word."
