I drive to games, home and away, so there is great attraction from me (apart from games in Edinburgh where I get the train and visit the pub pre-game).
I don’t remember drink being sold at matches, I remember 4 cans being brought in to be placed between the feet and eventually chucked depending on the outcome of the game.
I went to a match in Reading a couple of years ago, I struggled to down the pre-game pint, it was poor and I never went back for a half time drink.
