First, welcome aboard.
Second, that walmart understands that OC is legal. And your welcome for that. hehe I had an issue there with an Asst Mgr. I ended up dealing with another Asst Mgr, Store Mgr, and Asset Protection Mgr to get it straightened out. I have not had an issue since.
There are a few of us that OC in the Hickory area. We had talked about a get together and it never quite got off the ground. I do know of one restaurant in the area that is very OC friendly. Mama's Pizza. Great food too. Although the Walmart incident is the only one I have had in this area and I've been OC'ing several years.
