My local theater is OC friendly. I went to one movie and behind me I heard a woman tell the ticket taker, "That man had a gun!" He said, "Who?" She said, "That one that just walked by you!" I entered the theater not hearing the rest of the conversation, but nobody came in after me.
Another theater, I was getting refreshments with my family and a manager approached and asked if I was an officer. I said, "I am a Navy Officer." He asked if I had proof I was an officer, so I showed him my military ID card. He said, "OK, only officers are allowed to carry guns here." Weird. I guess enlisted couldn't carry in that theater.... :question: and this was in a standard civilian theater out in town, probably 1 hr away from the Navy base.
