The stories I could tell of poor theatre behavior encountered in my brash youth...
I recently saw Lincoln while visiting family in LA. I have never been to a movie theatre with assigned seating before. My Mother and I found a couple sitting in our seats, but a polite word saw them evacuating our seats for their own (we were in a party of 5 all sitting together). Just before the previews began, an usher addressed the whole theatre and reminded everyone that this was a distraction free environment and that she would be on hand to ensure it remained such. All I could think was where can I buy stock and open up a chain in my area of the country.
