He tells him, "I tell everyone about this kid and what a moron he is. Every time he comes by I offer him two quarters OR a single dollar bill. He takes the quarters every time...never learns." Right as they're talking the kid walks by the window. The barber knocks and waves him in. The kid walks up and the barber offers him two quarters or a dollar bill. The kid takes the quarters and leaves. "You see that? Every single time! I feel sorry for our future." says the barber. Curious, the customer chases the kid down and asks, "Why do you take the two quarters? You know one dollar is worth more, right?" "Of course I do, but the day I take the dollar, he'll stop paying me"
