glass that's on your iPad. Serwer : And that's a huge business. Huey : Sam Walton completely transformed the distribution business worldwide because he couldn't get anybody to distribute to him. He was constantly looking at his numbers. He realized a really important fact, and he asked the CEO of Procter & Gamble ( PG ) to come to Bentonville, and the guy said, "Well, you know -- " He said, "I think you'd better come to Bentonville. I have some really important business to discuss with you." So the guy came to Bentonville for the first time ever, and Sam said, "I've discovered something that I think you and I need to know before we go any further forward." And the guy says, "What's that?" And he said, "Wal-Mart accounts for more of your business than the entire country of Japan, and you don't even have anybody who will call on me in Bentonville, much less be based here. Everything's going to change. You're going to open an office here. You're going to treat us like we're Japan." And he pretty much did that to the rest of the world, and as a result, he ended up taking all the pricing power away from the manufacturers. I would say they were both some of the most difficult people in the history of the world to negotiate with because their idea of a negotiation was, if you said no, they didn't hear it.
