Alice watched the other guy as his hand dropped to his side, praying that he was armed and at least sort of knew how to use it. She bit her lip, waiting for the guy to relax his grip on her.
He did, eventually shoving her to the side, sending her slamming hard into the brick wall. She heard a dull thud as she hit her head, but it didn't knock her out. She'd end up having to call in sick for her first few days of work until her face healed up, but (hopefully) she wouldn't be dead. Finding her arms and legs functional, she crawled backward slowly, trying to get out of the guy's sight.
It didn't work.
"Don't move, or so help me I'll kill you and then take your wallet," the guy said, keeping his eyes trained on the new arrival.
