This Sonic was in DeKalb County, Georgia. I have never heard what Sonic's policy on CCW is in Oklahoma. Since Sonic is based here in Oklahoma, I would think that they would know how the people feel about CCW and being able to defend yourself. All I know for sure is that "Gun Free Zones" are just open invitations for robberies, mass shootings(Aurora, CO--etc.) and a "shooting fish in a barrel" attitude for bad guys/perps.

On February 8, a customer who ignored Sonics request that customers refrain from bringing guns to the restaurant was able to pull his gun and shoot one of three alleged armed robbers, killing him and stopping the would-be robbery.
