It's not because they are feeding homeless it's because of food handling and distribution laws so keep on trying. It's right in your article you never read.
Again... real facts mean nothing. Just like the Florida guy who feeds the homeless. He wants to feed them right on the beach and make a story of it. It is more about HIS personality than actually feeding the homeless. If he feeds them at a church where the facilities are then there are no TV cameras, no popularity, no press. What is the sense in feeding the homeless when it is not a big story?!
