If the society really wanted to make some dough, they would release a book covering the art of seat saving.
Several times we had people move our stuff and just take our seats. We had 9 in our extended family so we usually took up a good amt of space. The men in the family went early to get seats so the girls could stay home and get ready.
When I became a teenager I always wanted to sit with my friends. It was always interesting to see who got to see with who, it was very much a prestige thing.
Once I was sitting alone with a teen age sister and her father came and made her move since it didn't look right. I could have fell through the floor. LOL, the joke was on him, I was much more attracted to him that to his daughter.
