Last five minutes of my last hour at the reference desk.
Patron: " I would like a computer printout of the Passover dates for the next five years."
Me: "Didn't I give you a printout of national holidays for the next five years a few months ago?"
Me: "And...................What happened?"
Patron: Oh, I threw those papers away because I just read stuff and throw it away.
Me: "Well, that is not my fault! You should remember the dates since you had them before."
Patron: " I don't keep or remember stuff, just look it up! It's in a book back there."
So I give the patron a book of American Holidays and Festivals. By this time another librarian was on the desk and he proceeds to complain to her about the book I gave him.
I did look in one more book, but then I decided to leave the search and him alone. My time on the desk was over and I wasn't waisting my desk time on a search that I had done a few months back for the same person.
