A masked man with a sword messed with the wrong 89-year-old shopkeeper when he tried to rob a Washington state convenience store Sunday morning.

The would-be robber walked behind the counter at Frank's Superette in Moses Lake, Wash., and demanded that Miyo Koba open the register for him. But Koba, who's owned the store for 60 years, isn't so easily intimidated.

"I said, 'No, I'm not going to open the till for you,'" she told KREM, "'If you don't get your hands off the till, I'm going to stab you with my scissors.'"

"He started pounding on the register trying to open it because I wouldn't do it for him," said Koba. "He pulled out his little sword out of his little jacket, and he just kind of waved it a little bit."

Police say the "little sword" measured about three feet.

The suspect shoved Koba and took off with the still-unopened register, but while she was on the ground, she was able to reach for a golf club and beat him in the legs. She was aiming for his head, but couldn't reach it.

The robber escaped with his life, riding away on a BMX bike.

Police later recovered and returned the register, but they also found something even stranger: All of the robber's clothes.

"He must have been running around in his underwear and no shoes because that's what they said, they found all his clothes," said Koba.
