The man came into the popular Mount Pleasant restaurant after closing time, brandishing a revolver and demanding money.
For a few moments, employees didn't know what to make of it.
"We thought he was kidding and then he shot my manager," said one of several 911 callers in recordings released by Charleston County officials Friday night.
The calls paint a tense scene as Tavern & Table employees fought to maintain order and get help for Chris Dixon, the manager who had been shot in the back during the April 4 heist that remains unsolved.
Authorities say the gunman, identified only as a black male wearing a black sweatshirt, blue pants and a red bandanna over his face at the time, came into the restaurant around 11:30 p.m.
"It was a little revolver," one of the callers said. "It was pointing at my head. ... And then he shot my manager. We gave him every (cash) drawer. Then he ran out the door and shot twice into the kitchen."
At points during the recording, employees can be heard giving instructions to keep pressure on Dixon's wound.
Another person asked someone to call Dixon's wife.
"I don't think Chris even saw him," another caller told a dispatcher.
He is expected to survive his injury.
Investigators are still working to identify a suspect in the robbery and shooting at the popular restaurant on Shem Creek.
