Tevin Lopez watched the robbery unfold from outside.
He says two men ran from the east into the store.
Both men had 9 millimeter guns.
"One guy actually had garbage bags over his shoes. The other guy had white sneakers and a green ball cap," said Lopez.
One man pointed a gun at an employee. The other man pointed his gun at Lopez’s grandmother.
Lopez says the men took all the money from the cash register and a few cartons of cigarettes.
"It's pretty traumatic," said Lopez.
The suspects are white men. One stands about 6 feet tall, weighs about 160 pounds and has curly blond hair.
