Even though their founder and CEO was casually throwing out the slur on a call he had with his marketing agency about the PR fallout of his previous comments complaining about NFL players exercising their right to protest police brutality during the national anthem, the official position of Papa Johns is that they condemn racism in all forms and they want to distance themselves from the endorsements and praise the restaurant has received from white supremacists both before and after the slur came to light.

Unless it is the ones in Atlanta because I believe Shaq owns those.

Your source does not back up your claim. The founder said he didn't use the slur.
