In the expensive seats, yes. I was actually at Game 3 against the Lakers in the 7th row. I stood up for the last 2 minutes of a great game and a guy behind me poked me in the back and asked me to sit down. To our credit though, 30 seconds later the whole arena did stand up for the end of the game.
What the audience is thinking, "My goodness Olajuwon looks pale! Honey give me bi-focals! HOLY HEEPIN HORSERADISH! Hakeem is one of them there Oree-in-tails!"
