A lady came up to the Ref Desk today holding a spotty piece of paper. She claimed that the photocopier didn't print her document. A co-worker went to check the photocopier and I asked her if she was trying to copy it from the tray on top or on the glass. She gave me a befuddled look and said "I'm trying to copy it from the Internet" and then she added "You're machine said to add change so I put in 15 cents but I only have 10 cents left so I can't make another copy".
I pointed out to her that the "printer" that is attached to the public Internet computers was to her left and that she was trying to print her copies from the Internet to the coin-operated photocopier on her right. Luckily her free page of the day had printed automatically to the laser printer but I still don't think she got the difference in machinery.
