This happened on Tuesday night at the Rushmere Food Mart on Old Stage Highway and the whole thing was caught on surveillance video.
The robber made it from the parking lot, through the front door, past one clerk and to the counter in seconds.
The clerk at the register grabbed a display to hide behind and the gunman suddenly got cold feet.
But as he tried to back out of the store, the first clerk scrambled for the gun and managed to get it away from the robber.
The would-be robber was scared off by one man who took action.
No one was hurt and the suspect did not get any money.
The Isle of Wight County Sheriff`s office is asking for help to find him.
