I am actually very surprised and shocked by this thread. I was under the impression that any child under the age of 18 had to have parental supervision or permission, especially for the games that run into the late evening.
I know that it is a turn-off to enforce that a parent is present however for the safety of the child and the peace of mind that a parent is watching their children, it would behoove all event coordinators,VC,VL, store owners to insist this be taken into account when children are playing.
I know this is a family friendly gaming society however the real world is very dark place that has people who pose with good intentions but may have much darker motives. I have seen and heard of issues where a child was taken off property without anyone being aware, it is a very dangerous thing to let children be unsupervised by people who are not authorized by the parents to supervise children.
I hope this incident is not prevalent as it could be a serious liability to the store owners and potentially the PFS.
