A US woman has been convicted of punching a 70-year-old Walmart cashier during a dispute over a receipt on Christmas Eve.
Jacquetta Simmons was found guilty of felony assault by a jury in New York state.
The 27-year-old faces from 2 1/3 to seven years in prison under New York's Granny Law, which makes it a felony to intentionally injure someone 65 or older if the defendant is at least 10 years younger than the victim.
Prosecutors said Simmons knocked Grace Suozzi down with a blow to the face while Ms Suozzi was checking her receipt.
Simmons' lawyer argued she swung her arm but did not intend to hit Ms Suozzi.
Sentencing is set for November 14 in Batavia.
