Hey, @rebeccabe.

I've heard of this happening to people. I've thought about doing it, too, just to see how it would work, but I haven't yet.

It's amazing how paying it forward can have a chain reaction, where the next several customers in line do exactly the same. All it takes is one person to get the ball rolling.

Eventually, though, I imagine someone takes the generosity and walks away with it, perhaps grateful but unable to continue.
