In the second incident, they also took items from the employees.
No one was hurt in either robbery.
A clerk Albany Food and Liquor said their store has been robbed twice in one week. The last robbery was Saturday, when a cashier was pistol-whipped, and cash was stolen from registers around 10:45 p.m.
The owner of the store did not want to talk on a camera, but the owner of a business next door said it's concerning.
"It's very bad for anyone to rob the store. You know, nowadays everyone is suffering. They rob because people don't want to work; it's very bad," said Saroj Patel of Sara Professionals.
