I just got back from WDW so I have some new ones:
I know the whole cutting the line thing has been covered, but a new version of cutting in line happened to me this past week. So I'm walking up the single riders line for the Mummy ride (ok yah it's Universal) and you know you have to walk through a long line to get to the end of the single riders line cus it's usually very short. I consider myself someone who walks at a fairly good/fast pace. So I'm walking and this girl probably around 13 pushes past me and runs up to the end of the line. Now I know I hadn't reached the end of the line yet, but I had been walking through the maze of ropes for a minute and was almost there. Cutting is cutting... Anyway, she didn't say anything to me when I got up there and proceeded to try and bring her family up with her (aren't we in the single rider line?). Me and the people behind me were not having it though. This was a case where the single rider line actually took a long time too

so I had to stand behind this girl for awhile and I was just annoyed the whole time. BTW, 13 year olds (I would have guess younger if it hadn't been for her clothes) should not be wearing tight low cut tanktops, low-rider jeans, and have their thongs showing! They shouldn't even have thongs if you ask me!
Please stop your kid from picking their nose! Every kid I was around seemed to be doing this and their parents said nothing! I know it's natural for them to do, but the only way they'll learn to not do it is for their parents to tell them to not do it. I just don't want to touch your kid's snot when I grab the hand rail after them.
My sister and I were at the Indiana Jone Stunt Show, sitting on the end of the bleachers all the way on the right side several rows down from the top. They had already moved the rows in like they always do so there was absolutely no room. There was only several inches between me and the edge of the bench and I was touching my sister and she was right next to the guy next to her. So this woman comes up and practically sits on top of me and acts like I'm rude cus I don't move over more (there was nowhere to move)! When she sat down, she literally sat on my leg, I moved over as much as I could practically on top of my sister and this woman proceeds to tell me to move over more. Luckily the people behind us saw this and told her she could move back to their row since they had room for 3 people back there, which makes me wonder why she didn't sit there in the first place. People are strange!
Don't use the single rider lines then refuse to split up from your family. I saw a woman take her small child through the mummy single rider line and I'm thinking to myself this boy is going to be terrified alone. So she gets to the front and the guy kept telling her to get on the ride and for her son to go to another car and she was refusing to be split up from him. Several cars went by with no single riders even though there were spots cus she was arguing with the guys. The worst thing was that they were blocking the line so I couldn't get past them. The guy kept telling me (I was behind the pair) to come up and take a single spot but the woman and little boy wouldn't move. I finally had to push past them. The guy kept telling them to move out of the way but they kept lingering there and kept trying to get on a car together even though they weren't assigned to it and he would pull them out of the line and put people from the real line there. I got on a car finally and they were just standing there when it drove off so I have no idea what happened to them, but that was certainly annoying to all involved.
If the CM gives you the card to hold for you to carry to the front of the line so they can time how long the line is taking, don't just toss it on the ground. If you don't want the "responsibility" then tell the CM you would perfer not to do it so they can give it to the next person or if you change your mind part of the way through, try to pass it to the person in front or behind you. I can't tell you how many people I saw just toss these on the ground. Timing the lines is important for everyone so they can provide accurate info for people riding.
OK, I know the whole moving all the way over thing has been discussed, but for some reason this happens in every single show I go to still. What irks me is that the same people who insist on stopping in the middle of the row are the exact same people who insist on pushing their way to the front of the crowd and hover in front of the door in order to be first in the theater. I guess these people think that whoever is in the theater first gets their choice of seating first or something. If they were smart they would realize that staying towards the middle or the back of the crowd (depending how many people are there) in the "holding" room before you enter the theater would allow them to get in the center of the row once they get into the theater, but I suppose logic escapes some people.
If you don't like smoking, don't sit in the smoking section and complain about people smoking. There are a million other places to go sit. Oh also, don't smoke right into your kid's stroller, I can't tell you how many times I saw this. I know you need to keep your kids with you, but I found it disturbing how people would be blowing smoke in the direction of their children. I feel bad just smoking in the vicinity of children. The worst was at MK I saw 2 women sitting there smoking and both had a child with them. They were just chatting away and one of the kids started coughing uncontrollably. The woman kept yelling at him to stop coughing. I'm thinking to myself, he's probably coughing cus of the smoke you nitwit! Not to mention you can't order someone to stop coughing nor should you be so insensitive to do so.
Oh another disturbing/funny no-no I saw this past week was people trying to scam their way into the park. A family with 2 kids were standing there arguing with the guy at the ticket machine. They didn't speak English or were pretending to not understand. The guy kept telling them that they had already used all the days on their tickets. He even mentioned the days they used and where they went. They were just holding up the line trying to pull a fast one. I was talking to a CM later on who told me that he encounters this a lot with "foreigners." He said a lot of "them" come here and are always trying to scam or get something for free or cut corners in some way like cutting in lines and whatnot. I'm sure he didn't mean all foreigners and I'm sure it wasn't only foreigners who do this, but it was funny cus another CM mentioned something similar to me after I tipped him for serving me a drink. He mentioned that I must be American cus the foreigners don't tip. Neither of those CM's probably should have said those things to me, but it just baffles me to see some of the things that people try to pull at the parks. I can only imagine working there how much they see and have to put up with.
