A Seahawks fan visiting Candlestick Park for Sunday’s rematch between Seattle and San Francisco was issued this prissy warning card by ushers instructing her not to stand in the seating area during play.

I just got yellow carded by the 49ers. Sorry for being a #seahawks fan? #FortyWhiners

The woman posted the card on Instagram, which naturally prompted fellow Seahawks fans to chime in with messages like, “that’s why they’re not the loudest stadium in the NFL!”

There might be some truth to that, though I hear it is still possible to make noise without obstructing the view of other fans. Either way, the 49ers have had just about enough of your being standing.
