We were at the jazz game with donated corporate tickets down low.  A couple of times in the game, I see people kick people out of their seats using their tickets at various times in the game, same sections/seats by us and elsewhere.  It's like people bought an option for lower down but for only half a game, and then had to sit somewhere else for the rest of the game.  In each case it was people showing their ticket to move the others out, and the others had no problem leaving even though they kicked the others out before them.

Weird, never seen that before.  Is that a thing to buy only half a game in the premium section?
