Living in Georgia, the major thing this law does is eliminate a state ban on guns in certain types of places and leaves it up to the establishment itself.

Of course, it has led to some absurdity already: http://politics.blog.ajc.com/2014/07/02/on-new-gun-laws-first-day-a-draw-down- in-valdosta/

At approximately 3 p.m. Tuesday, police responded to a call regarding a customer dispute at the Enmark on the corner of Park Avenue and North Lee Street. A man carrying a holstered firearm entered the store to make a purchase. Another customer, also with a holstered firearm, approached him and demanded to see his identification and firearms license, according to the Valdosta Police Department report. The customer making demands for ID pulled his firearm from its holster but never pointed it at the other customer, who said he was not obligated to show any permits or identification. He demanded the man’s ID again. Undeterred by the drawn gun, the man paid for his items, left the store and called for police. Authorities arrested Ronald Williams, 62, on a charge of disorderly conduct, related to the pulling of a weapon inside of the store, according to the VPD. Police confiscated Williams’ weapon and took him to the Lowndes County Jail.
