I will always say something when a guest is abusing a CM. They can't say anything, and I can tell you from experience that they appreciate the support of the sane guests.
I'm a bit disappointed in all the people who say that they will ignore it; that it's none of their business. This attitude (and even moreso the attitude of businesses who give these people freebies for being horses' patooties) are the reason why people continue to act this way. We regulate behavior in our society by our response to it. People don't dare do some things for fear of what other people will do in response. If these jerks were outnumbered by people who would make them feel like the idiots they are, they would stop.
I would love to tell the story about the piece of work who made me cry as a CM (later on, after the rage subsided), but just thinking about it infuriates me all these years later. I wasn't the typical CM who just stood there and took it. I had my say, but I still wish someone with no restrictions would have helped out (and someone who wasn't about 150 pounds lighter than this guy, like I was).
Kudos to the wife who told off the man at the
Disney Store. When the whole store applauded, only a complete moron would not be embarrassed into changing their behavior. That man will think twice before he does that again.
As for arguing between guests in the same group, I am guilty. One of my exes and I got into a fight EVERY time we went to WDW. I know; I should have ended it the first time. Well, the third one was the ultimate break-up fight. It was embarrassing, but sometimes you just have to get out of a situation. I did wind up yelling at him to give me my keys so I could go home.
Someone said that if you're that unhappy at WDW, you need help. Well I don't know about that, but you do at least need to rethink who you choose as your travel-mates.
