Examples of what the signs read include: "Kill Obama," and "Obama & Muslims not welcome here."
Some signs target other famous people in the Black community, reported Mic.
"Colin Kaeper-dick, you overpaid half-breed: Take your millions and go back to Africa," the sign read.
“It's been here a long time,” former employee Marlon McWilliams told KOB 4.“… If you go in there and you offend him (the owner), you can't go in there no more. He turns lots of people away."
The store is currently listed for sale for $359,000.
“I wish somebody would buy it,” said McWilliams. “I really do, because it would be a great asset for somebody to be there to run it. Because that's the only place you can go to get milk and bread.”
The owner of the store has not been named and has not commented on the signs.
