I guess that I am an old softie.
IAD - AMS, had an aisle E+, family wants to sit together.
The purser asked me to move to an aisle, E-.
I did; had a couple of free drinks; still slept most of the way.
The hardware was a 777; I don't think I would have agreed, had it been any other AC.
Neither of the parents involved (Americans since we're into ethnic slurs) even said thank you. In retrospect, it probably doesn't suprise me.
I honestly don't know if I would agree again.
At least for a couple of years I'll be inclined to think that I served my time, already did my duty, etc.
