 Too much of an error. And if you'll think about, today we have credit cards, so you don't have to wait. You just pick up the phone and tell them what you want, give them a few numbers, and it's all over. I wonder how much you would purchase if you had to pay cash. If there were no credit cards and you had to go and walk in wherever you're buying something and you had to pay cash, probably not nearly as much as people do purchase. There's something about waiting we don't like.
