Honestly, we didn't run into many rude people on board at all, and if we did, it was more than likely a teen ager! DH was pushed badly by one teen girl who was fighting with her parents about not taking "one more formal night picture!!" - she almost knocked him over! And when the kids did the show on the last day, I had some of those "too cool for school" teens and 'tween boys sit next to me, and try to make fun of the kids on the stage...I said something to them, because I'd expect someone to say something to MY kids if they were acting like jerks...they stopped, and then started applauding along with the rest of us. Good thing too, let me tell you...
Where we DID see rude people was on the excursions and getting on/off the ship...then it seemed to be "everyone for themselves" and lines, which many waiting in patiently, were apparently only there for SOME of us.

And if they were rude, they were over the top rude, to the point of being ridiculous, so we tried to ignore them and laugh it off.
The ones saving the chairs? Well, as I never SAW any of the "owners" of those chairs and the towels that were on them, I can't say if they were rude or not! *grin*
But in general, honestly, the atmosphere on board was like a big friendly community, with strangers talking to one another at the slightest little thing...people who cruise often tend to be the outgoing, gregarious happy types who like to share, and we're all there for the same reason, to share in the Magic...so that's what I paid attention to.
