A Nebraska woman allegedly found a lucrative quirk at a gas station pump — double-swipe the rewards card and get free gas!

Unfortunately for her, you can’t do that, prosecutors said. The 45-year-old woman was arrested March 6 and faces felony theft charges accusing her of a crime that cost the gas station nearly $28,000.

Prosecutors say the woman exploited the system over a period of several months. Police learned of the problem in October when the loss-prevention manager at Bosselman Enterprises reported that the company’s Pump & Pantry in Lincoln had been scammed.
