I've given money when I have it to those guys, a buck or two, sometimes five. The way I figure it, no one does that unless they could use the money. There has always been an exchange of smiles and thank yous and please try to get to a shelter if you cans. Never any cussing or sour looks that it wasn't enough or attempts to wash my windshield. I was heartbroken last week when I saw a young man looking a little rough sitting by an intersection with a sign. It said, "Just hungry."
