Security video from the Advance America branch clearly showed the man's face during the stickup Monday, and a 23-year-old surrendered Tuesday on a preliminary charge of robbery.
Police say the robbery took an unusual turn after the gunman came around the counter when the clerk starting crying and talking about God.
The man said he had a 2-year-old child to support and asked for prayers about overcoming his hardships.
Police say the man removed the bullet from his gun and gave it to the clerk before taking her cell phone and the money.
