Pay for other people's drinks: leave an amount of money at a coffeebar and tell them to give away coffee until the money runs out. An idea from Bart

Actually i didn't make this one up myself, i borrowed it here: http://www.good.is/post/people-are-awesome-the-south-carolina-coffee-shop-where-everyone-pays-for-everyone-else-s-drinks
I like the idea, i would love to see a video of people's faces when they get their coffee for free. (offcourse: make sure that only fair-trade coffee is served with your money :)
If this idea wins, i will donate some money as well!

Wow that'd be really fun :D I think I'm doing it the next time I go to a coffeebar :)
