You charge through the putrid rubbish and throw yourself desperately over the bonnets of cars. Just as you edge past the truck, which is leaning dangerously on the side of a large van, you spot your goal.
You stretch out your arm in a futile, desperate attempt to grab the sandwich, which is just out of your reach, next to a tyre of the van.
Suddenly, the van moves, screeching across the road, and the truck is falling on you! You stare in disbelief at the metal coming to crush you...
What will you do next?
