Acting Like Animals
I worked at this zoo, which had strict rules to ensure the safety of the visitors. Kids had to be accompanied by adults, there was no late or early access and food was not allowed because of the way the cages were set up.
My coworker had had enough and decided, on a tour, to give the most incorrect information about the animals as he could. He allowed kids to come in with teen guardians that day and also encouraged them to buy a snack and come back to see the tour. It was hilarious and management had a field day with it.
