There are some man-made creations that are so blasphemous that God cannot allow them to exist. Things like the nuclear bomb come to mind. Their power is too great. They have to be stopped. One such creation is the six foot sub. It's just too much sub, especially to be wielded by one person. Like the person who tries to open Pandora's Box, trying to harness the power of such a sandwich can only ruin you. That is what happened to this poor soul.
The power of the sandwich was too great for him. It crumbled in his hands, much like his crumbling dreams. It's perfectly fair to find a piece that hasn't touch the floor and to eat it though. I think that goes for any food that you drop on the floor, especially an eighty dollar sandwich.
