Lago di Garda, Italy
Husband and I came across a very angry American woman pounding the front of this machine.
“Don’t use this #%#*$ ATM!” she warned us. “It’s out of money. All you get are these stupid IOUs.” She held up several packets of square stickers.
Me: “Um, this is the Post Office. And this is a postage vending machine. You bought stamps.”
Woman: “What the f*ck am I supposed to do with a hundred dollars’ worth of Italian stamps?”
I managed to drag him away before carnage ensued.
