On a lighter note and not to detract from the seriousness of the subject. I was recently on a flight from Paris when, during the flight safety briefing, the mobile of the elderly man in the seat in front of me went off. He was wearing those aids that go behind the ears. It was as loud as a doorbell. Anyway, he was instructing a delivery driver. Meanwhile girl is in the middle of he spiel and udiot tries to show her where the package was left only for her to tell him that she was a bit busy.
So, trundle down to take off position when the doorbell goes off again. He is told quite firmly to switch it off but proceeds to arrange a lunch appointment.
Icing on the cake was he then reclined his seat on a 40 minute flight,
