Broken Robot Burger Bar

Dumped on Planet Earth, some broken alien robots wander the wastelands trying to find a purpose on this idiotic world. The broken robots needed cash for spare parts, and so they got jobs flipping burgers for the man. The robots thought the humans were strange. “Why do humans love grease? Why do they squeeze the burgers then eat them? Why pickles?” The humans thought the robots were strange, but the burgers were tasty, and no-one bothered to inquire further. Which was a mistake. Silly humans. Because after work the robots are transforming the burger grill into a robot minting machine. Any salvaged scrap will create a broken-but-not-defeated robot! But why? Well, they have a plan. And they have written it on a piece of paper somewhere. The revolution begins with the mint.
