I wish Too Good To Go was in use in my city. My friend lives in Oakland and she uses it all the time. She said it’s a bit hit-or-miss, though. She’s shown up at some places and they’re like, “here’s a bag, fit it up with whatever and we’ll charge you $n for it.” Once it was a shelf of stuff and they said she could as much stuff as she wanted from the shelf for the same price. Once when I was visiting her, we got a huge bag of baked goods. If nothing else, it can help familiarize you with areas and businesses you may not have come across otherwise.
The Third Man has that fantastic zither theme.
