Well if they sold nice beer I’d imagine that would change.
How much revenue do you reckon American stadiums make from ale?
Then again I think you’re probably just being a judgemental twat.
Let me tell just an example that proves the point. When the Carolina Panthers were awarded an NFL expansion franchise, the downtown Charlotte stadium wasn't ready for the first season. So they played their games at the largest university stadium in the area, about 90 minutes away in South Carolina.
What they found out last minute was that South Carolina had a law about serving beer within a certain distance of a church on Sunday, and some group of ministers decided they would foist sobriety on just 8 NFL Sundays in 1 NFL venue, for 1 year.
They called a special session and changed the law.
This August, I was in Colorado and took a tour of the Denver Broncos' Mile High Stadium 2: Horsey Boogaloo. As part of the tour, they showed us the beer dispensing and storage facilities, and said that on average, between 600-700 kegs' worth of beer is sold on an average Game Day.
/and yes, that is primarily a cold weather venue
