Tell you what happened to us at the Safari, we were loaded on the truck, the truck was full, we were on the last row, there was 3 of us including my mom.
This guy in the seat in front of us, had his wife and child and he kept looking around back at the queuing area. Just as we got ready to pull away, he stands up, tells the driver to STOP. They think something is wrong, and the CM on the loading deck rushes over and asks, "what's wrong". This other couple they were with had just shown up and since we were the last to load they wanted them to take us off and let the late couple have our seats.
The CM, was like are you serious, No way am I going to take these people off. Why were you not together in the line? Do you really think we are going to wait, for someone else to arrive and let you hold up the truck? You can get off and wait at the end with them, or you can go on and catch up at the end of the ride but we are NOT taking these people off the truck.
He stayed on but he griped out loud and mumbled about it the entire trip. Which ruined it for my mother, she was really upset as he kept turning around and glaring at us. The driver was watching him so when we got to the end of the ride, he told us if we wanted to ride again he would take us to the front, but we said no we were going on to the Trek, so he gave us a fastpass for any ride, any time and we went on.
We saw the idiot a couple of times during the day and it was all I could do, not to go up to him and say you really are a piece of work. But figured he would go off and that would really upset my Mom.
Some people at Disney are the rudest I encounter anywhere.
