WTF, Salesman Edition; or Ground-hog Day in July?

So, I'm sitting at my desk yesterday and the phone rings. I answer it (that's what you normally do when a phone rings, right?) On the other end, some guy in a loud and hearty voice (think "friendly carnival barker") asks me how I'm doing.

Me: Fine.
Him: Great! Every day closer to the weekend is a good one!
Me: Sure.
Him: I understand you order the printing and toner supplies there. Is that right?
Me: Well, yes.
Him: Great! For every order you place today you get your choice of a Kindle Fire or a camera. (empahsis and italics in his spiel)
Me: no thanks, we're not ordering today.
Him: Well, I understand that, and that's why I'm calling. For every order you place today, you get a Kindle Fire or a camera.

WTF, dude? Did you not hear me? I'm not ordering anything! I say so, nicely, and he repeats the same offer! I end up hanging up on him in mid-pitch.

Then, the same guy calls me again today! (Just now, in fact.) He launches the exact same spiel and I say "didn't we talk yesterday?"

"No, I don't think so," he replies, and makes the same "order and get a Kindle" pitch.

After we go through the same dialog above (I swear to God, the same!) I end up hanging up on him.

In what universe does this shit work?
