When this conversation started, I had already had a very frustrating morning. I was on a corporate website, trying to learn a procedure.
Unfortunately, all the instructions involved acronyms which were not included in the corporate glossary (although, they did take the time to define what a bag was used for).
So my brain was already sore when this call came in.
Note - this is a newspaper office.
Caller "Hi, I was looking for information on an event that was held at {location}. Are you familiar with {location}?"
Me "No, but we have people who are. What kind of information did you need?"
Caller "I was looking for video of an event my buddy was involved in. It was in 2001."
Me "Um...well, we only have still photos. We're a newspaper and we don't take any video."
Caller "Oh, okay. What about still photos?"
Me "Well, we don't have them back that far here. Your best bet would be to try the library. They have microfilm of our paper going back to the 1950s. All you need is the date range and you can scan the papers for a picture."
Caller "Oh, I don't have a date. My buddy said it was in 2001. Or it might have been 2002."
Me "Well, if you ask the reference librarian for those dates, you can look them over. It will be a couple of hours in a nice warm library."
Caller "Okay, thanks! I tried calling {radio station} first, but they didn't have any video."
(In the caller's defense, the radio station sponsored the event, so it wasn't a totally unreasonable request, although I'm still not sure why he thought a radio station would have the equipment to video an event.)
Me "Have you tried {local TV station}? It seems to me that if anyone would have video of an event, it would be them."
Caller "Thanks! I never thought of that!"

Me "You're welcome, have a nice day!"
He was a nice guy, but my brain hurt when we were done.
