This could have ended very badly. Luckily an off duty cop was at the school too.

According to WYNT, a 50 year old grandmother Anita Bolster went to pick her grandchild up at Cambridge Central School on Friday afternoon. An off duty police officer was there to do the same and smelled alcohol on the grandmother's breath. An on duty officer was called and made the arrest. The grandmother reportedly had a blood alcohol content of .18, more than twice the legal limit and actually had an open can of beer in the car at the time.
