I agree with you on that. That is why I am asking what the reason is for continuing to do it. There has to be one.
Speaking of business side of sports, this actually ties to the bathroom lines. Clear the concourse to make it easier for people to give you their money at intermission. If you're going to add a new concession area / beer stand then maybe put more than 1 register there. Seems like it takes 1.5 minutes per customer to take an order, pour a beer, and complete the transaction. You're not selling too many beers at intermission if you only have one person handling that.
That might cause a riot in Milwaukee! People take their beer pretty seriously in Wisconsin. (One example was the Badger football team playing in Las Vegas. They had a pregame party and ran out of beer in 90 minutes. When the Badgers came back 4 years later, the guy running the party
tripled the size of the beer order for the Wisconsin fans.)
At the Panther arena, the stands usually have 2 people working the cash registers on the main concourse except for Saz's and the place that you get garlic fries (or deep fried fish on a Friday night). The Panther Arena seats 9650 for hockey, but the largest crowd this season was 7500. I am pretty sure that you can buy 16 ounce cans of beer even at the popcorn/candy stand.
The place with the most beer stands that I have ever seen at a hockey game is the Blue Cross Arena in Rochester, NY. That had 4 or 5 beer only stands set up
in the concourse as well as the usual places built into the arena, probably 20 stands that sold beer as well as other items. There were a few guys walking around the stands selling 24 ounce cans of beer for an arena that officially seats 11,200 for hockey, but with the upper ends covered over, it probably seats 7600. That was more places than the 17,875 seat Bradley Center had to sell beer. At a large stand at the BC, they might have 4 cash registers going, a smaller one would have two.
