It has happened several times over the years. Once in Austin when we were playing UH and the lady told me she was just there to see the bands. I get that one-Wow, a UT fan shush me during an ou game for being too loud....WTF!
Uhh, that person would get a very hostile and nasty response from me. Out of kindness, I won't speculate here what I know I would state.
probably someone’s mom there to see them play at halftime. But, our group has has to endure the golf clap/sitting on your hands “fans” since before I went to Texas- 1976. Admittedly,
we are extraordinarily loud- at every game-
home or road.
