Hahaha! XD
Darn rich people.
>>6 sure it's illegal to buy stuff with gold directly but it's more of an investment. You buy gold and watch the prices fluctuate. Also, gold is kind of a global currency. It's probably better to invest in gold if you fear your economy because it's easier to cash gold in a different country than it is to trade your overly inflated money.
Of course, that still doesn't justify a vending machine for it. But you gotta love the japanese for trying to cash in on any demand that exists. XD
