Here's the set-up from FoxNewsInsider:
Last Sunday, at a Valero gas station in L.A. a glitch was made in the system – gas that was supposed to be $4.29 per gallon was calculated as $1.10 for premium unleaded. Everyone that pulled up could see that they paid about $20 instead of $60. No one said a thing, and the station owner lost $21,000 in three hours. What would you have done in that situation?
