There is no aggressive "you HAVE to buy this product" tone or "attitude." Instead we are told why the product is good (cool, comfortable, hygienic, etc.) and why it has a place in your home, and not just Ashok Kumar's. The product is also presented as part of a bigger story. You can see the ad here, and while some might find it too simple and utterly low tech, it scores on quiet, dignified courtesy. Even now.
