One Christmas I took note of how much money the SA kettles raked in. It was over $100,000.
I also drove a street person to pick up his Christmas box from the SA, noted there was nothing in such that was not donated, including the labor, the food, the gifts. So where did the money go from the kettles?
The same 'used to' hold true with their Thrift Stores, getting all free, even the labor, and then selling it back to poor folk at nearly new wholesale prices, only freely giving to those who grovelled.
