Post your interesting story... I was once in a Fry's near Palo Alto, and a guy mistook me for a store employee. Started asking me all sorts of questions about a cable for his PC, and as I was helping out, I noticed that a couple of other people were waiting behind him to ask questions. I thought it was amusing, so I went on helping out. In any case, the guys in the store completely ignored me, even though they passed by a couple of times. I never did mention that I didn't work at the store, but hey, why not?
