In-N-Out’s famous burgers have been hit by a fresh wave of criminal mischief—only this time, the suspects traded beef for bogus Benjamins.

California’s legendary fast food chain was rocked as two daring women allegedly pulled off a spree targeting not one, not five, but a jaw-dropping 21 locations across Los Angeles County.

The suspects, hailed as ‘female hamburglars’ by cops, slipped dozens of fake $100 bills past unsuspecting cashiers—netting themselves plenty of change by ordering only bargain bites like fries or the ultra-secret ‘Flying Dutchman’ (that’s two patties plus cheese, no bun). Glendale PD dropped the details Monday, identifying the duo as Auriona Lewis, 24, and Tatiyanna Foster, 26, both from Long Beach.

“They kept their orders cheap so they’d rake in the most real cash as change,” revealed Glendale’s Sgt. Gaik Pobokhian, who dubbed the dollar drama the city’s latest ‘ketchup caper.’

The rip-off train came off the rails late October when a vigilant employee at the Glendale In-N-Out flagged down officers after spotting one seriously questionable hundred-dollar note. Detectives soon discovered the scam was playing out all over LA, and Perp No. 1—Lewis—was nailed thanks to her car’s license plate, visible on store surveillance.

The hunt for Foster ended on December 15, with police clapping her in cuffs amid mounting evidence. Investigators released jaw-dropping images of the identically numbered notes, and a full rundown of their orders—fries, Flying Dutchmans, and a mountain of ill-gotten change.

Estimated losses? Cops say it’s a few thousand dollars pocketed in the scam. Lewis faces felony charges of grand theft and counterfeiting, which could land her behind bars for up to three years. She was busted carrying counterfeit cash matching those passed at the very first Glendale heist and has since posted bail.

As for Foster, her fate is up in the air until she appears in court later on this month. Stay tuned for sizzling updates on this high-stakes burger bust.
