Human Billboard?

Miami has plenty of what we call "street hawkers" who work at all major intersections to collect cash for different causes/reasons. I was puzzled to see the back of this man's shirt today and learned that the Homeless Voice organization has these vendors who work full time collecting money for them wear this kind of shirts. The "vendors" may be former homeless or drug addict persons and they are now working for some income. They get to keep 60% of what they collect (about US $40 - 50 a day.) The rest goes to the Homeless Voice organization. They say the money goes to support their homeless shelters. It is a big controversial here because of the ads you see on the back of the shirts of the street hawkers. They carry advertising slogans. This one is obviously for a law outfit seeking business from people hurt in accidents. I don't know about you, but that tactic stops me cold from parting with my cash.
