Hm? No reason, just wondering.
And in completely unrelated news: "Through a series of carefully controlled experiments at a campus bookstore, researchers learned that consumers will, in every case studied, spend more money to buy a brand name item when someone they don't know is standing near them at the time they choose their purchase. Consumers also tend to spend more money when a group of people is standing near them but are more inclined to buy cheaper items when no one is near." [via robotwisdom]
