After midnight it undergoes a startling metamorphosis from Safeway to Dangerway - the spiked pits and rings of fire come out and the supermarkets turn into arenas for an extreme game show somewhat akin to American Gladiators where contestants compete against each other, wild animals and killer cyborgs to win free groceries.

Think Mad Max beyond the Thunderdome with shopping carts instead of souped-up motorized vehicles.
