Surveillance video from inside the shop captured the entire robbery.

After the gunman demanded cash from the register, the owner ran outside to get help.

To the surprise of those still inside, a customer who happened to be an armed security guard went after the robber. He ran outside after the suspect and opened fire at the suspect’s car, which left a pile of broken glass in the parking lot.

“I didn’t even know it was shots,” said Archie Grant, who works in the same shopping plaza. “Not this time of day, not here.”

Many in the plaza were shocked when they realized what was happening. One person said she heard 6 shots.
