Two clerks at a Mapco in Donelson were robbed on Stewarts Ferry Pike.
The clerks told police a woman and man came inside the convenience store and demanded money around 12:03 a.m. Sunday.
One of the clerks said the man nudged her with his shoulder, pushing her towards the registers.
She said he never pulled a gun during the robbery, but she did see one in his waistband.
The suspects got away with about $25.
They fled in a white SUV, but so far, no arrests have been made.
