Disrespect at a car show.

It's not just kids and not just at car shows. When I was a D.I. at MCRD San Diego, I witnessed this kind of crap every Thursday and Friday. I can't tell you how many times I went into the parking lot and caught people sitting or leaning on my car and buddies cars. They were usually middle aged and over weight. Many of them got a small taste of what their son's had just listened to for 3 months.
