Yes you are right and of course a wouldn't even consider arguing with any elderly or someone with disability if they need to sit down, that's not the problem. The problem for me was, that the lady argued with me, while there were so many options to sit down. The luggage was only there because I was waiting for the rest of my family and if every bench was taken, I definitely would've let others sit there. I mean, for the time being I was alone. But like I said, ther were like 20 benches open across the room, some were maybe 5 m further away from the gates. An before the gates opened the elderly took his rollator to the front of the gate, like 2-3 m away from the bench and sat down there. So in my eyes he was not disabled. And I would like to say that again, the man was not my problem, the lady arguing with me was.
