At some point they eliminated that whole thing, and now just let everyone

Two years ago I had a few of the non-aviation types in front of me
during the airshow. When the show was over they stood up and started to
walk away, leaving their trash behind them on the ground.
I called after them and told them to pick up their trash stating, "We
don't leave trash on the grounds here."
Despite his indignant glare, I stood and pointed to the mess they had
left. He came back and picked it up, but was not happy that I publicly
pointed out his littering.
