The idea that someone else might screw you for the money is not the point.
Wouldn't you like to be a better person than someone like that? I mean everyone complains about what a rotten world we have and yet when it comes right down to it they act the same. Maybe there's no tangible reward for doing something like giving back 20$. I felt good on the times that I did something nice for someone for no reason so you do things your way and I'll do it mine.
