Picture three scenes.......
Long haul overnight flight, say SIN-LHR, a fairly full A380, 3 -4 hours in the light, the dinner is long past, the lights dim and most drift off to sleep.
Ring Ring, Ring Ring, Cue long, loud & inane half-shouted partial conversation of complete irrelevance to the rest of the flight. Passengers start to wake up, grumpy about even more disturbed sleep.
Conversation continues, waking up the cabin in an ever expanding series of ripples.
Second scene, similar situation.
Ring Ring, Ring Ring, Ring Ring,....... ad infinitum as the owber snoozes peacefully whilst the rest of the cabin wakes and seeks the source of this disturbance....
Scene three......
fairly quiet flight with a number of empty seats.
Ring Ring, Ring Ring,....... Hi Mate, long time no hear,....... No I'm flying home just now,.......No kidding, what flight?....... No way - I'm on the same one, what seat?...... yeah, I'm in 23A, plenty room no-one else in the same row. And so on for the next ten miutes, with neiter of them intelligent enough to actually move about the cabin to sit beside each other.
Anyone taking bets on how long before we have an airborne brawl?
