These guys are mad because Chill's and other fast food companies released a statement this week stating: Open Carry is not allowed in the restaurants.
I'm trying to figure out the need for people to bring guns to a food spot. Imagine the panic some people felt when they first saw these guys walk in. The kids were probably like

His white baby mom probably some fat hillbilly from the same trailer park as his lil crew of got nothin' better to do's.
Would be me if i managed that place too. These redneck dudes would probably be the same dudes to get upset if someone was naked in public in front of their children, yet they think other parents with children enjoying a meal should have to suffer the presence of douchebags with enough weapons slung ocer their shoulders to kill everyone inside.
Even the NRA released a statement saying these type of dudes are clowns who hurt actual firearm rights.
