I have a friend who does. I think he does it also when I am not around to see. But I am not like that. I usually pick only those most obvious in need. My thoughts and emotions are often mixed. Sometimes I see beggars who were recruited to be beggars and have their managers taking share of their profits. That gets me really mad. It makes it difficult to recognize 'genuine' beggars. Sometimes you just don't have enough coins. Is it a just justification? Should you always have enough coins?
