A few years ago I went to Shangai. When I boarded the plane in Amsterdam, I met a first class idiot as soon as I stepped foot on the aircraft.
When I got to my seat, the overhead bin was already full, so I had to store my bag on the other side. But when I tried to do that, an idiot came from nowhere and started screaming at me. I didn’t understand him, but I got his message: “That’s my seat, and I want to store my bag there.”
I grabbed my bag, walked two rows down, asked the person who was sitting there if it was ok I placed my bag in his overhead bin; he said yes, I stored my bag, walked down to my seat, and sat down.
Was that difficult? No. Could the idiot have done that? Yes. He didn’t have to make a scene.
