October 24, 2007 -- A tiny but fearless shop clerk stalled a robber pointing a gun at her head - then swung a giant ax wildly at him until he ran from her family's Long Island convenience store. Hafize Sahin, 27, all of 4-foot-5 and 90 pounds, was working alone in the store on Montauk Highway in Brookhaven Saturday evening, Suffolk Detective Lt. Edward Reilly said.
