First,
kevind65, I worked at Six Flags Over Texas for about two years, and we had a policy that no foul language nor drug related language was to be on any clothing at any time in the park. Most of the time, the guests would be stopped at the front gate and asked to either change clothes or turn their shirts inside-out. You wouldn't believe how many people would turn their shirts inside-out, walk 20 feet inside the gate, and then proceed to turn them back.
I was a supervisor for a year or so out of the two years I was there, and I always "loved" being called to a situation to find an irate guest cursing their heads off at one of my employees. The one good thing about those situations was, in a very calm voice, reminding the guest that they were in a family park and to watch their language. Most would calm down, but I was well known among the employees as the one who wouldn't put up with it. There were several times when, after being warned more than three times in one conversation regarding language (as in "I'll f***ing speak how I want to f***ing speak"), I would simply call security and have them escorted out of the park. Most of the time they were young teenagers, but I tossed some adults, too. My favorite was a father who had totally blown up at a ride operator for not letting his child, who was 6 in. too short, ride. His wife and other older son looked mortified with the way he was acting. He was warned several times and finally I made the call for security. He cursed at me even more, and his family was trying to get him to let it go. Security arrived and I explained the situation. Lo and behold, he started changing his tone and language altogether...trying to fool the security guard and blame me for overreacting. The security guard simply told him he should have acted so politely to me, because I was the one having him thrown out. He went right back to cursing. As he and the guard were walking out, he looked back at his wife and said something about following him. She said, "No way...you can go sit in the car Mr. Potty Mouth, we're going to enjoy our day!"
Sorry it wasn't a Disney shock...but shock nonetheless!
