About 40 minutes before landing, the cabin speakers started playing some music. An air stewardess approached me and asked me to turn 'my music' off. I pointed to the overhead speaker to indicate where the music was from. She turned around and walked off, without apologizing.
I understand that she may have been mistaken, but I am concerned that someone who couldn't tell where certain sounds are coming from yet has access to some controls and levers of an aircraft.
