Imagine getting into an autorickshaw and at the end of the ride being told that someone has already paid for it. Or after a fabulous meal at a restaurant, instead of being presented with a bill you get a handwritten note that says it was a gift from a guest! Sounds implausible, doesn't it? Well, you might find yourself more at the receiving end of such "random acts of kindness" as the concept of gift economy takes shape in India.
