Get seatbacks!!!One time our kid came over and sat with us for a few minutes. Yes, we had 5 people with only four bought, but we were pushed into just under 3 seats. We asked the rest to please move down, they complained we had an extra, I pointed out that we were only in 3 of our four which was quite common. After that, we came in early and anchored our four seats and the group sitting in the middle would complain about space. Their own seats weren’t enough apparently.
