I just had a storyline about a modern day Robin Hood story, a group organizes a event that at a certain time all stations in a certain area that are pumping gas for a short time have a glitch and sell the gas at 35 cents a gallon like it was some years ago.
The device is portable and they run around southern CA using it secretly, nobody knows where or when but instead of paying $50 of 10 gallons you pay $3.50.
