A couple of years ago I was at a USMTS race when the Scott brothers were at the top. The grandmother of the Scott brothers and a few others sat right in front of me. Every time one of them was on the track she stood up the entire time.
I politely said to her something like, I understand you're excited to watch them race but I can't see anything when you're standing up. Would you mind sitting so we could see? She responded with "My grandsons are #1 and #2 in the country, I spent $1 mil to get them there. I deserve to stand up if I want to."
We ended up moving to some crappy seats but it was still better than being behind her.
