Not seen such Bravery!
I believe the laws apply to sports, not stadiums. I've had beer watching rugby at the Millennium Stadium but I wouldn't have been able to drink it at the play-off final. Can't see the Amex being different
Absolutely.
This is rugby we are talking about. It is almost illegal not to drink at your seat when watching it

There is simply no way a venue would have been chosen which didn't allow pitch view drinking. The rugby authorities would have insisted, and no drinking would have meant no selection as a venue.
