Depends on where you were sitting. Most of the time, CMs will tell guests that they need to stand up....I know that when we were in the FP+ area for Wishes, the CMs told everyone that sitting down wasn't a good idea!!! Of course,, there was that one woman who decided to jump over the fence behind me....I told her I was standing there...No, I was there was her comeback. Hardly....I had been there for over 40 mins, with my dd and her friend, leaning up against the railing that runs along the walkway by Casey's. She argued with me, I told her that this was a reserved section and she wasn't entitled to be there.....she ran off, into the crowd, with a CM trying to find her.
Or the time my dd and I had followed CM instructions, and stood along the parade route down in FrontierLand. We were told to stand in a specific spot...where the roping goes up, along our side, to allow for a walkway to the restrooms. So, there we stood...until about 10 mins prior to the parade. A woman with a stroller came along and asked us to please sit down...her child, in the stroller, couldn't see the parade. I told her we were not sitting down, that we had been there for about 30 mins and had followed a CMs instructions. She whined and complained to a different CM, who then proceeded to ask if my dd and I would mind sitting down so that the family behind us could see. So, down we sat....I'm 5'8'', dd is 5'10'', both have really long legs. That woman had pushed up so close behind us that we had about a 2 sq foot area to sit in...without our legs going past the roping. It was miserable. And that child in the stroller? Slept the entire time. I actually overheard the woman say to her friend...'See, you don't have to get here early to get a good spot. The CMs will always try to make you happy..so just complain about those in front!!!' Seriously.
Or the time my dd and I were in front of the Emporium, watching the afternoon parade. There was, again, an open space for walkers to get through. This was the parade that had CMs on bikes, drawing stuff and handing the drawings out to guests along the route. Dd and were right up along the rope, one of the artist CMs pointed to dd, rode over and handed her the drawing. BUT...the woman behind us swooped into the empty spot for walkers, grabbed the drawing and scampered away!
There is a ton of rudeness any time you get a large group of people in one spot. I count on karma making it back around at some point for each of those rude people.
