When it comes to scamming Uncle Sam, fraudsters hatch some very complex plans to milk entitlement programs. But when it comes to defrauding the federal food stamps program—it can be as easy as pushing a button.

Recently, a husband-and-wife duo from Waco, Texas plead guilty to charges of food stamp abuse that allegedly scammed the government of $350,000

Magdalena and Jamal Akhter, who run a convenience store, allowed customers using Supplemental Nutrition Assistance Program (SNAP) debit cards to choose the “cash-back” option when buying items—something that’s not allowed under the program’s rules. The two then pocketed half the cash and paid the SNAP beneficiary the rest.
