Here's a dispatch from Planet Money's Chana Joffe-Walt, who just arrived in Greece.
My first moment in Athens was someone yelling in English, "Americans, step right up! Best day of your life! Welcome to Greece! Gets better every hour!"
This was the guy selling euros at the currency-exchange kiosk at the airport. A dollar buys more euros today than at any time in the past year.
Him to me: "What an exciting time to be an American!"
Me to him: "You think so?"
Him: "Of course! Best in a long time. Yes, yes, yes! Bad for us but so good for you. ... Until it's bad for you, too. And then let me tell you, that's not fun!"
