A couple of decades ago I gave a dollar to a guy begging in front of a grocery store. When I was leaving I overheard him telling the security guard that he's taking his family on vacation next week so he won't be around. Then I watched him walk all the way to the very furthest spot in the parking lot, get into a brand new van, and drive away. I was pretty pissed off because I was poor myself and a dollar meant a lot to me. This dude was taking from poor people by acting poorer, when he actually had enough money to own a brand new van and take his family on vacation.
