The video emphasiizes that for successful communication, you first have to find a "Common Interest" or a "Bond" with your customers, and then build you marketing strategy based on this platform..
If you fail to do this, the chances are your customers would ignore you, no matter what you're trying to say. This is mainly because they wouldn't pay any attention to your subject as they cannot identify with it.. hence a "sausage" would provide a more innteresting topic than the subject itself..
This video is taken from "Coupling" one of the more popular English serials, that shows the worldview's importance, in a funny way.
