Today's 'clever' customer came in to ask about printing films from his digital camera. While I was trying to think of a polite way to tell him that digital cameras don't actually have films, it transpired that he was referring to a particular photo printer and wanted to know more about it so I showed him that model and then another, more versatile one. I talked for several minutes about the printer and the ink cartridges needed for it and then, interrupting me in mid-sentence, he suddenly said,
"Oh, I'll have to go and get the paper. My wife will think I've got lost."
With that, he turned tail and charged out of the shop.
Something I said................???
