So I take my son to a local video game stop--you know, one of those that sells used games at a discount. How can you turn down a used version of Zelda: Oracle of Ages for the Game Boy Advance for a pittance of $4.99--cash? Turns out, of course, the game didn't work well--someone resold it in for a reason, I suppose.

No sweat says the cashier. Within 30 days, all returns are refunded with a receipt.

So I bring it back the same day and explain the situation. No sweat. Same cashier takes my receipt and starts typing away. After about four minutes, she looks up and says: name, address, phone number. "Why?" I ask. It was a cash transaction. Her brilliant answer: "Because you're returning the game."
