Personally I don't see any difference between this and paying for a train ticket and being unable to sit during the journey. So yeah, I think it's fair. Whoever comes first gets the seat, and keeps the sit if they want to. It's not like you are renting the seat per x minutes or something.
When you are in park do you bitch about people sitting on benches for too long?
I'm not asking for justification. You think it's fair, and I respect you for that. I may have a different opinion, and that's fine too! It's just that it seems dishonest to deflect a question like the politicians do.
