A Facebook social networking community raised nearly $10,000 for a California food bank after a good samaritan asked what she should do with a $93 gift.

It started after Carolee Hazard of Menlo Park, Calif., helped Jenni Ware of nearby Redwood City pay her grocery bill in a supermarket.

Ware discovered as she was standing in the supermarket checkout line that she'd misplaced her wallet.

Hazard didn't know Ware but was standing behind her and volunteered to pay Ware's $207 grocery bill. Ware promised to pay her back.

Ware later found her wallet and paid Hazard $300, suggesting she spend the extra $93 on a massage.

But Hazard asked her Facebook community what her friends would do with the bonus money, the San Jose (Calif.) Mercury News reported.

The Facebook friends urged Hazard to give the money to charity, specifically to a local food bank since the act of kindness took place in a grocery store.

Hazard, a green activist and former Genentech Inc. biochemist, loved the idea, the newspaper said.

She not only sent in the $93 that Ware had given her but matched the amount.

So did one Facebook friend after another. Some donated $9.30. Kids pitched in 93 cents.

Hazard then started a Facebook "93 Dollar Club," about the "random act of kindness that snowballed."

The page includes links where people can donate to food banks close to them. Commentators from Australia to Portugal, Turkey to the Czech Republic and Iran to Sri Lanka are donating, the newspaper said.
