From the Doncaster Free Press website:

and cheaper aswell. will it be on sale just in the main bars, or also in the concourse. looks like concourse aswell.

only thing is, if its on in the concourse, a barrel of real ale would not last from one game to the next. so id guess once they run out during half time, instead of putting another barrel on, would they put the sold out sign up. or can the beer be transported to the other bars, even though its been opened
