Good Movies: The Girl in the Cafe

There is a man on my commute who walks the median of a busy intersection, holding out a paper bucket for contributions.  His need is pretty obvious.  He limps horribly because one of his feet points behind him.  His lower leg is twisted around and it hurts to watch him walk.  At least it hurts me.  On the other hand, I have rarely given him money.  But I have often wondered about the thoughts of my fellow commuters.  Do others feel this pain?
