When I'm open carrying, I walk up to the entrance to HEB with the firearm visible. I literally pull out my T-shirt and put it over the pistol as I step across the threshold.Agreed. A 30.07 sign just means put your shirt over it and don't be a dumbass. Or, if you're going grocery shopping, plan ahead instead of throwing a tantrum. All the angst is silly.
They know I'm carrying and they know what I feel about their signage. Everybody comes out ahead, I think.
