I Don't Need to be Told...

... not to get off a moving transport until it comes to a complete stop.
... not to tamper with the smoke detectors in the airplane lavatories.
... that there even are smoke detectors in the airplane lavatories.
... how to buckle my seat belt.
... to take my "personal belongings" with me when I leave. (or my impersonal ones for that matter)
... to have a nice day by a recording.
