I dropped by my brother's shop one fine day, as I often do, and the tamale guy who comes by every day was there with a flat tire. This is a middle aged hispanic fellow who is extremely poor and barely keeps his tamale cart/trike thing cobbled together. My brother is well aware of this and wanted to get this guy going again so he could keep making money selling his tamales. So, he pulled out some used tubes, I gave him my set of Maxxis Hookworms (both front tires were absolutely trashed) I had left there as take-offs from a previous build and my brother charged him something like 4 tamales. Guy was extremely happy, my brother had breakfast set for the next two days and I got to get rid of a set of tires I was never going to use, it was a win-win-win.
