British posters please chime in (unless you are Gokkunfan, who I can barely understand). I have never seen anyone doing anything "sporting" in bars here and I have no idea how it works.

"One Staffordshire pub hurriedly axed its 25-year-old dominos team, when police discovered that it lacked a license for sporting activity. Once the landlady had acquired a license, though, she discovered that nobody would be allowed to watch the dominos, since this would constitute a live sporting event and require a further license."
