Hilarious or is it SO WRONG?

What would your reaction be?

So I was on my way to eat at a restaurant today with my parents and brother when a man walked up to us. The strangest thing happened. He asked for a few bucks to buys something to drink and eat, but I've noticed that he had on really nice clothes. I totally almost fell for it. I mean, I wouldn't mind giving change to those who really need it. But this man, well, he was something. He had a ring on his finger. What's hilarious was that he tried to hide it from us. Well, that didn't work. We just ignored him and entered the restaurant. About an hour later, we exited the restaurant and found the same man walking towards us. He asked the same question. When my dad rejected him, the man then said, "What do you mean? You just came out of the restaurant. Don't you have change?" I know, how ignorant and selfish was he?! My dad knew that the man had money, that's why he refused to give him any. My dad was so furious that he exposed him. Yeah, it was pretty embarrassing, but I think that he deserved it. So, my question to you all is, how would you react if someone approached to you and disrespected you?
