A bandit with an apparent craving for a snack held up grocery store cashier at gunpoint in the Tenderloin neighborhood of San Francisco and made off several cans of potato chips, police said.

The junk-food robbery occurred around 4:40 p.m. Wednesday at a store in the 500 block of Larkin Street and police were still searching for the assailant on Friday, officials said.

The female suspect entered the store, whipped out a firearm and demanded the cashier to fork over property, police said.

Instead, the cashier, a 32-year-old woman whose name was not released, ran out of the store in fear for her life, police said.

When she returned, she noticed that the suspect had stolen a cans of chips, police said.
