Oregon has a law that children are not allowed on the premises after 9pm not sure what state you are from but obviously this is bad for business. I would discuss it with the bar owner and get his angle on it. He may be fine with it...who knows.
Obviously a bar is no place for children to be running around unsupervised..which sounds like the case. What is it with parents these days anyway
Some states have laws regarding taking children into places where smoking is allowed, is this a non-smoking bar? Can't believe people subject their kids to second hand smoke after all the data available on the subject.
Repost with the bar owners slant on things...It will be interesting to see what he or she thinks.
