When a man pulled two guns on convenience store clerk Wazir Jiwi and
demanded money, Jiwi asked how much he wanted for one of the guns. He
said $100, which Jiwi paid him. Then Jiwi offered to buy the second
gun. The robber handed it over, grabbed the cash and headed for the
exit. But Jiwi had pushed a button under the counter that
automatically locked the door. "He turned to me and asked what was
going on," Jiwi says. "I told him to bring the money back and I would
let him go. He brought the money back, and I opened the door."
