When I went to barcade in dallas, it just seemed so alien to me to see these kids running around in a bar. Mainly because there were several alcoholic beverages that were left unattended. Just seems like a real easy way to loose a wine and beer or liquor license. you might as well close up shop if you loose that.
There was a restaurant/bar local to me that got their ass in a sling a few years back because of that. Bad experiences usually dictate policy.
