We were flying back from BKK in July, and it was about an hour after dawn. The cabin was dark, blinds drawn, most PAX sleeping.
Until one of the two <redacted> on the East side of the cabin pulled the blind up to look out at what could only have been the ocean. It was like someone had set of a small nuclear device.
If I thought I wouldn't have got arrested I would have thrown something at them. Maybe some luggage. Or an anvil.
It was completely unneccesary, disruptive, and inconsiderate.
Many hours earlier the pair (a middle aged married couple) were complaining to the FA about their gluten free/wheat free/veganvegetarian f*#%ing meal and carrying on like a pair of 3 year olds.
So, the etiquette? Try to be considerate to your fellow pax. Of course you can't please everyone, but p*%#ing everyone off is not the way to go.
