The victim of an armed hold-up at a Corowa service station had to be treated for shock after the brazen incident.
The pair entered the business about 1.15am on Saturday.
They threatened the female attendant, and one walked around the counter as the other jumped the counter.
They took cash and a large amount of cigarettes.
Detective Inspector Winston Woodward said he hoped people may have been driving past at the time and caught dash cam footage.
They were last seen running towards town.
