When I lived in NC, I thought it was worth it. I don't frequent places where alcohol is served because generally I do my drinking at home.
I do like beer with my pizza, but I rarely crave pizza anymore.
I suppose that IF I had, on occasion, gone with friends who wanted to eat at a restaurant that served alcohol, such as a steak house, I COULD have done so without any problems IF my friends had not noticed I was carrying before we went, because that would have meant my concealment was good.
Of course, that's ALL hypothetical, and I would never make such a recommendation.
However, I also believe, as others have said, that the more people who have permits, the more the crime rate drops, and the more used to the idea people get to allowing concealed carry in more places. It also gives gun-friendly politicians useful numbers for when they advance good gun laws.
