I don't think it helps when the crew look, and worse, sound, completely bored at doing the safety demo. I fly predominantly with low-cost airlines from East Midlands, so appreciate the crew might be on their fourth flight of the day after six days, but still, if you don't appear to be interested in presenting the safety information, why on earth would people be interested in watching you? I always watch, not only out of courtesy, but because I know all the statistics at how much your chances of surviving an incident are if you watch the demo (plus as someone on the outside of the industry looking in - hopefully changing soon - I'm fascinated!) But I'm not the average passenger obviously.
