33-year-old Lisa Woodhead was working at an e-cigarette store in South Yorkshire, England when a robber came in with a HAMMER.
He demanded all of the cash from the register, but instead of giving it to him . . . Lisa decided to reach out and GRAB HIS JUNK.
And they stayed like that for 15 MINUTES: He kept threatening her with the hammer, she kept a hold on his package. Finally, some other customers walked in, saw what was going on, and chased the guy off.
Lisa wasn't hurt during the fight . . . and she was definitely fired-up after. She told a reporter, quote, "I didn't feel much in my hand, so I wouldn't say he's too well-endowed."
Police are still looking for him.
