I am along the lines that if they are making any type of effort for the money, then I usually give them some. Anybody can sit on their ass and yell at me as I walk by. Some of them I swear wisper they speak so low, but you know its coming the moment you see them there. I always acknowledge their presence and say sorry or that I have no change though. I think its important to at least show them that I at least have the respect to answer their question. In China it was unreal. The beggars that I saw there were the most deformed humans I have ever seen. One guy had no limbs and just laid there on his stomach with a tin can in front of him and he just kept bobbing his head. I was told that these people are severly taken advantage of and are dropped off and picked up everyday by their "caretaker" and that most of the money does not even go to them. It was very very sad.
