Eaten Anyway

I asked a window to give me some work. It said there were very many repetitive tasks available and asked what kind of thing was I looking for. I said I was looking to exchange my time and basic limb-manipulation skills for cash I can spend on things I won't remember.
Yes, it said, I have some work for you, tonight, in the Stuff Parade, you have to stand at the end of a tunnel while bits of stuff come at you and you decide whether that stuff is good stuff or bad stuff. Bad stuff goes to the left where the electric boffins furrow their brows at it until its purpose emerges. Good stuff meanwhile gets put in a shipping container which is then loaded onto a massive cackling boat and never heard from again.
