One Saturday, Reb Shlomo was walking up Broadway, and a young man came up to him and said, "Give me your money!" Reb Shlomo turned to him and said, "Brother, it's Shabbos today. I don't have any money on me. But if I see you during the week, I'll give you a five, OK?" And the man let him go. And during the following week, he actually saw the man who tried to stick him up and called, "Hey, brother!" and ran after him. And the guy ran away, probably figuring that Shlomo wanted to get even with him or something, but Shlomo caught up with him and with hand outstretched said, "Here's the five that I promised you." He really had a beautiful sense of compassion.
