Placards on tiny tables didn't bother me nearly as much as the high volume US Airways destinations ad reel that played after takeoff on our 6:45am flight.
The TV in front of our seat was broken, playing only static. All the patter and none of the breathtaking vistas!
I complained to the flight attendent about the mix of loud ads and broken visuals. She told me to ignore the cacaphony and go to sleep.
