Today while we were walking in a foreign country, a beggar asked for money to feed himself and child (he had no child with him.) We gave him what change we could (less than 1 Euro) and he demanded more, saying it wasn’t enough. We did not give him more (having given to other people who asked earlier); thinking he could accumulate enough by asking others. He became upset and through the change away! Then he walked to another place, put on a leather jacket and went on down the street asking other people for money. We’re we wrong not to give him more money, perhaps a few bills?

No, you were 100% correct.
