If he acted normal. I would actually be intrigued by it's vapor production, but since the guy is acting like an immature over eccentric child or ass, he obviously has no value for his Public Image, and therefore has no value in his own products as he doesn't seem to be worried about scarring potential customers off by acting like a loony. Which means that he is just a punk degenerate loser who has no vision of quality being demonstrated to his watchers, and who has nothing to lose by making a fool of himself on video. The childish attitude of the salesman is proof enough there is something fishy about the product. In my book. If the sale man doesn't take the product as something worth respecting and going in to detail about with professionalism then quality of the product is obviously being hidden. I would urge extreme caution based on the video to buyers.
