I didn't watch the vid, I just read the quote. I thought he was getting the same seats every time because whoever owned those seats never came to games. If he did it the way you said, I'm assuming his tickets scan to get in the arena but if someone is in the seat or comes later, you just say "Is this your seat? My bad." And get up. Watch from the crappy seats he originally buys. If you can do that, you can finangle anything else. Theres a couple who has been sitting next to my girl seats for like 20yrs she said, since she was a kid. They know that if we don't go to the game and they have friends who are also at the arena, they can sit in our seats.
Just like the movie theaters with reserved seats. I may buy seats to the movie but if no one shows up to sit in the better seats, I just switch like 30min into the movie. They not coming.
