Kaptin M,
It is a company requirement that we mention the seatbelts in PAs to the passengers.
This is in the hope that, after being hit with this message several times, the passengers will actually wear their seatbelts while seated. How many times have you heard of passengers being injured in unforecast turbulence? How many of these people have probably not been wearing their seatbelts while seated? How many of these people would then blame the airline for not being adequately briefed - see my other post above.
Surely you are not suggesting that this REQUIREMENT is just preempted by the cabin crew (storm troopers) in a fit of pique aimed at discomforting the passengers?
