Fwiw I don’t really think $6 per 12 ounces is all that expensive, certainly not cheap and it should be cheaper but I’m pretty accustomed to seeing 5-7 bucks for a beer at bars these days. But it is definitely absurd to expect a family of four to spend like $150 dollars per game.
The bigger issue is food and soft drinks imo, I can’t even imagine what left field would be like if you get drunk on the cheap.
