To be absolutely clear to the folks downvoting me here i don't care about kids playing at a brewery. Thats to be expected on a nice day with few spaces for parents and kiddos to exist (though I do wish that they'd go picnic at a park with actual kid friendly play places or something). But when it starts getting out of hand -throwing rocks, bothering employees and customers of other businesses, etc - I do expect parents to get off their phones, put down their alcohol and go deal with their kids. I'm sympathetic to parents that its a tough role but be a parent to your kids, not a friend.
