I would add that I boarded in the last group of maybe 10 people. There were literally 4 people who boarded after me. They had obviously gotten lost or something and didn’t turn up for a good 15 minutes. I did not go stand by the door and block anyone at any point.
I was always considerate. Maybe they did decide I was a trouble maker but I didn’t ask them for anything else at any point. It was only when being served that I had questions.
My experience of international v domestic seems to back that up.
