The place I used to work had shuttle buses to transport employees to and from the parking areas. The accepted etiquette is that when getting off the bus, the people in the first seats get off first, then the next row, and so on until it is empty. Except for one man. He always would get up from his seat and run to the front of the bus so he could be the first one off, even if he'd been way in the back. He was generally considered odd and a bit rude, but no one ever said anything to him about it. This went on for years, so it's not like he was unaware of the accepted protocol.
Eventually there came a time that I sat next to him. He was in the inside seat by the window and I was in the aisle seat. As we approached the stop he started making moves like he wanted to get up so he could make his "run." I did not move. The bus stopped and people started filing off as usual. He asked me to move for him. I put on an innocent face and said, "Oh, it's not our turn yet! I'll move as soon as it is." and ignored him.
I guess I was rude for not moving when he asked me to? I don't know. I liked that I made him wait his turn like everyone else.
