Maybe you should put the signage on the doors, instead of letting concealed carry permit holders walk in and buy tickets before you belatedly inform us that we’re not welcome?
Not that we care. My wife and I walked right past the sign with our guns, and enjoyed the movie. No matter where you put those signs, they don’t have force of law in Delaware. We can carry concealed in there whether you like it or not. If you noticed – which was rather unlikely – all you could have done was ask us to leave.
