Worthy?

"I give tzedaka (charity) to 100 poor people on the assumption that I may find one out of 100 was worthy and I will have the merit of helping him. But you refrain from giving to 100 poor people …lest one of them be unworthy. Therefore know that the average beggar who holds out of hand is presumed to need the money and you should not concern yourself hidden matters.”  Rabbi Chaim of Tzanz
