Last night, just before closing there were very few guests for IJA. When we were at the end and our jeep pulled in to the unloading area we were behind another jeep. When that jeep was filled up and sent on its way instead of bringing our jeep forward the CMs left us at a distance from the gates. They then called out to the young man that was sitting in the 'drivers seat' that we were stalled and he should give the jeep a little gas. The guest started looking around on the floor board for the gas pedal and the CMs kept calling out encouragement. "Pump the gas" "Jiggle the ignition key" etc. The guest is trying very hard to follow all of the instructions and other people in the jeep are giving him advice. Then the CMs bring the jeep forward suddenly, all the while saying to him what a great job he did. It wasn't until we were walking out the exit that somebody told him he had been pranked. He did not look too happy.
