- One vehicle, fully fueled
- Two sets of car keys
- One cinder block or wood plank
Drive to the mall. Cruise parking lot until you find a premium parking space.
Park the car. With the engine running, prop the cinder block or plank so that the brakes are engaged.
Put the car in reverse. Get out. Lock the car & take spare set of keys.
Go shopping, secure in the knowledge that you will ruin the day of at least a dozen drivers (per hour!) waiting on your empty car to back out of that awesome parking place.
