Even paradise has this problem. My cousin worked in Waikiki and took the bus to and from work. She told me of a story where she spoke to a local boy who begged for money at a red light everyday. She passed him when going to and fro. He told her that he gets over 100.00 within an hour. He then moves on to other lights an hour at a time for a few hours.
There is also a story here about a guy who begs at lights everyday and lives in a mansion!
But the best is this guy who I see all the time not to far from my town. Begging at a light walking with a limp(a really bad limp). One day I seen him RUNNING with his girlfriend to a bus stop because he didn't want to miss his bus. No limp, no nothing! ugh!
