North Korea is out of money, literally. They're revaluing their currency, and the method seems to be "turn in all your money now, and we'll give you new money next week." They new money doesn't get handed out until tomorrow, but the old money stopped being legal tender on the 30th of November, so nobody is doing any business there. Hopefully no one forgot to get their grocery shopping done on the 29th?
You'd think there would be more efficient ways to handle something like this, but it is North Korea after all i suppose.
