I really don't know why everyone's making a big deal out of my comment. To be honest, the "bums" in my town are usually dressed in clean clothes. And I heard a story once that somebody gave $50 to a "poor person" at the mall, and later while they were leaving, they saw that "poor person" hop into a brand new mercedes-benz....
Conclusion: most of them in my town try to scam people. Me, I don't trust any of them.
