I struggled with this too. “Ushers,” I guess you can call them. A buddy and me tried to sit in section O, which is general admission and were told to go sit in the upper decks because that was the only GA seating. We didn’t sweat it, just walked one section over and sat. Section O is indeed GA.
The game day crew is just doing what they’re told. I think (know) that what they are told is not always consistent. It never will be.
We’re all trying to live in a Covid world. Ask Norte Dame. In an act of defiance of social distancing, several thousand people rushed the field after they beat Clemson. Honestly, it was refreshing to see. Masks and all.
If there isn’t a story about that and maybe a fine on Monday, you have a story. I’m pretty sure the majority of the university and all of the fans on the field could care less.
