Talking endlessly.
I get that the new hip airlines like a certain amount of banter over the aircraft speakers, but let's keep it reasonably under control. On an overseas flight last summer on Continental, an attendant took to the microphone every half hour or so to release almost every pent-up notion that came to mind. It's a flight, not an improv club or poetry slam, yeesh. Let us watch the bad movies, catch a nap and get out of here.
