My Dad has always said the we should give money to people on the street. That we shouldn't worry about what they'll do with the money - that's their lookout; our worry should be about giving. Now, that said, my Dad has also arranged his life so that he's rarely in a position where people are asking him for money. If he's out driving and see's someone he can pull over and ask them or he can keep driving. I on the other hand am constantly accosted by people. I never have cash so that I can truthfully tell people I don't have money to give them. I avoid eye contact and have been embarrassed when a person asked me for directions and appeared to actually want directions to a place. The thing I really suspect is that giving money really is about you not the person you're giving it to. That when I have had cash and handed it over it was because I actually interacted with the person acting and I just couldn't imagine myself as a person who would rudely tell another person asking for help "no" and then walk away.
