MAYBE in twelves months time there might start to be an increase when the stuff is actually open. But for now the new boxes have simply replaced the old boxes. They have also been shut for most of the season anyway.
Spending £3.50 on a pint in the new stand, instead of in an old stand, doesnt turn the £3.50 into £5 just because you're in a different area.
Crowds are also down aren't they? So less people buying less stuff will cancel out one hundred people paying extra for a padded chair.
Good ideas, yes. Not extra money yet. If ever.
