MSP to CVG, was really into this movie Django Unchained, heard the announcement over my headphones but waited for an attendant to tap me on the shoulder or anything--and I would have turned it off and put it away immediately. They walked by and had to have noticed but nothing. I was shocked. Watched my movie completely uninterrupted. Only thing worth noting is that I was last to board, and greeted all of the staff with a smile and a hello when I boarded. And was very polite when requesting a cocktail.
