Here's an '80s clip showing the partial workings of a food bank. 

A sign reads, "SF AIDS Foundation Food Bank." 

A food storage room has containers of packaged bread, a crate of oranges, bags of carrots, and other produce. A large shelf is packed with boxes and bags that appear to be filled with food. 

A worker grabs canned goods and places them into baskets, likely putting together a donation for a person or family in need.
