I watched it a few times and am convinced that he knew something was wrong- ie his car disappeared- and the fat F went back to attending to his gas can in an instant of self-denial. Fat F threw the gas pump nozzle as an external public display while most of us would have dropped it and run after the car.
Hey, I've been there. Nearly tru mowing the grass, you run outta gas so now drunk on your ass and you have to go buy some. Under those conditions it takes 100% concentration to get the gas in the can.
Brought me to the realization that with 12million people over here wanting to work cheap, that I had no reason to be mowing my own yard.
