So here am I, plugging away in my nifty little computer shop, when in comes a customer. No big deal, that happens all the time.
"Hello," says customer, "I need a USB extension cable."
(For those of you following along, a USB cable has both an "A" ending and a "B" ending. Extensions always plug into the "A" ending.)
"Oh yes," I say, just as pert and perky as can be, "those are right here. Six feet?"
"Mmmphm." (People say that around here, you know.) He's looking at the two ends of the cable, and looking mildly distressed. I showed him how his cable would plug right in to the end of the cable in the package. He's still not happy, I can tell.
"What's the matter?"
"Well," he says, "that's not the end of the cable I wanted to extend."
