I've honestly never noticed a sign anywhere I go, including movie theaters, Walmart, etc. I guess they are up there, but I know where I'm not allowed to carry according to the law, so I just make sure I don't carry into schools or government buildings.
As for gun shops, if I'm getting a gun looked at, I usually carry it into the store unloaded, with the slide open and ask them to do the work necessary. I've never pulled a gun out of its holster to have work done. I don't understand the signs, but if I'm ever asked if I have a loaded gun, I guess I can simply choose to leave at that time.
