I see Burnham has announced he's looking at lifting the ban on drinking in view of the pitch because it's out of date and discriminatory against football fans. Having experienced fans drinking in the stands in Europe, I don't think it's discriminatory at all, having been soaked by lager when MGW missed the penalty in Graz.
I guess it may not happen in the Trent End (although there are a few idiots who'll occasionally lob stuff towards the front of the stand), but I can see away games being a bit of a nightmare. There used to be a group who'd jump around in the concourse and lob their drinks in the air at half time (haven't seen them do it for a while; maybe the extraordinary price of beer has put them off), but no matter how "good" the stewarding is now compared to when the ban was implemented, they'll still lob pints in the stands.
They'll also have a handy receptacle for when they need a piss; aside from having piss lobbed at you, it also means that fewer goals will be scored as everyone knows teams always score when you go for a piss.
