There's been quite a few incidents of drunken bad behaviour and violence at the principality stadium when Wales play. A copper told me it's getting worse than Cardiff city home matches.The Principality Stadium in Cardiff now has a large section where alcohol is banned on the terraces, as the true rugby fan was getting fed up of the 'part timers' continually going back and fore to the bar during the game. The seats are some of the quickest to sell out, suggesting a total ban would be popular to rugby fans.
