Stanley said she has since been fired from her job.
"I didn’t know if they had guns," Stanley said. "I didn’t know if they were going to their vehicle to get another one and could come back and try to get to the safe, so my instinct was to go to my car and get the gun."
Stanley said she was only trying to protect the store and her co-workers, and didn’t expect to be let go.
"For trying to protect their Waffle House, and trying to protect their money and to get their money back, they let me go," she said.
A Waffle House spokesman said that they are aware of the situation, but cannot comment on personnel matters.
Stanley said she was just following her instinct and would do the same thing again.
The robbery marks the third Waffle House robbery in Coweta County since September.
Authorities haven’t said whether this latest robbery is connected with the other two.
The police report made no mention that the waitress would face charges.
Stanley, a mother of two, said losing her job is a huge blow to her family because she is the sole source of income.
"(I’m going to) take a step forward and keep moving on and try to find another job," said Stanley, who added that she has set up a GoFundMe page.
