A vending machine that dispenses gold.
But unlike your local laundromat’s quarters machine, each piece of gold comes with a certificate of authenticity and the machine is jacked into the Frankfurt gold market so it can update its prices every few minutes. After that it tacks on a 30% fee, which all said and done is a hell of a lot, but so is any tourist piece of crap. Expect 500 more of these machines to pop up throughout Germany in the near future.
