Nothing too juicy here....
On a flight back from YYZ recently, the person across the aisle was constantly letting the crew know that they ALWAYS flew first on this route, and could they go and sit up in the empty first cabin, as they ALWAYS flew first on this route, blah blah blah...
Of course, the answer from the crew was no, sorry, that cabin is closed on this flight. But that didn't stop them from trying the metaphorical hang up and call again with different members of crew.
The crew didn't let on that they were getting a bit fed up with them, as they were too professional. However they were definitely a lot warmer towards me than them, as I was happy just to be served dinner and left alone! Where as the DYKWIA was pestering them for virtually the whole flight.
