In some cases and in some locales, the beer and other drinks come during the game.

I've seen plenty of that, too.

Some of our county parks used to allow canned beer if it was accompanied by food, as with a picnic. They used to ignore beer drinking in the parking lots after the games, too. However, all the county parks are now completely alcohol free. In fact, some township leagues request that the umpires call the police immediately upon observing consumption of alcohol anywhere in the park.
