Sheriff's deputies in Volusia County are looking for a man who they say robbed a 7-Eleven in Deltona Saturday.
It happened just before 10 p.m. on Providence Boulevard.
Deputies say the suspect got increasingly angry because he thought the employees were taking too long to hand him the money.
No one was hurt.
Investigators say the suspect was last seen running down Tivoli Drive.
