Once in a while, while intoxicated, you might end up taking a couple hundred dollars out of the ATM that you really shouldn't have. It's not great, but it's also not the end of the world. But if that ATM could dispense solid gold? Well, that opens the door for much more destructive mistakes.
In (where else?) Abu Dhabi's Emirates Palace, this ATM offers up gold coins up to 10 grams in size with customized deisgns whenever you want. It monitors the daily price of gold and adjusts its rates accordingly, so you know you're paying the proper price. And really, this is very convenient. I can't tell you how many times I've needed a hunk of gold at 1am and just couldn't find a place willing to sell it to me.
