Old people fight for ten cents because they are very old and their lives consist mostly of watching Walter Cronchite and sleeping and sometimes if they're lucky they can still taste the food that goes into their mouths so they can actually find joy in something. And then someone tries to steal ten cents from them. Those old juices start flowin, the adrenaline runs wild, and the least they can do is scream "give me my ten cents" to feel alive again.
