Street Gleaning.

Every couple of weeks or so this box appears on the corner a few blocks from my house with this sign. I'm not sure if it's put out by someone who works at Safeway and is trying to help out hungry people or if it's just someone who is rethinking their purchase of a trailer full of potatoes, but it's always the same thing; a box of kinda old looking potatoes and a few other random food items thrown in.
The food and box are usually gone the next day.
