Here in St. Louis (well, Eureka, actually, 25 miles west of St. Louis), Six Flags is overrun throughout the season by large packs of disadvantaged wild animals whose tickets are provided by the region’s well-intentioned (and utterly stupid) business community. The animals rampage for free, and make it impossible for human customers to enjoy their day.
If I were the Six Flags CEO, I would have the legal dept add a clause to the ticket contract: "Ticket purchaser assumes legal liability for all behavior of person admitted to park under this ticket". Then arrange for the businesses to very discretely be notified of the new clause.
My neighbor had season passes for there a couple of years ago. Some people called out a guy for cutting in line and the guy got in neighbors face screaming obscenities and threatening him in front of his kids.
At the StL zoo we were with our grandkids and there were lots of school buses in the parking lot. There were literally packs of these kids pushing everyone else out of the way.
Any guess what the common denominator was in these incidents?
