And now I'll drag out my old pet theory:
I travel solo. From now on, I'm just going to take potty breaks, snack stops, rest breaks, FP runs, etc. as necessary.
Then when I get to a ride, I'll excuse myself through the queue up to the point where I feel that I
theoretically would have been had I not made all the stops along the way. I'll skip ahead past all of those people who went ahead and got in line earlier than me.
That's only fair, right? Why should I be punished because I don't travel with a warm body to be sent ahead as a scout in line?
Heck, this is a great idea. I'll ride Peter Pan after lunch to make the most of it. So the plan is:
think about riding Peter Pan at 12:30 (this is when my imaginary placeholding touring companion enters the queue), instead go to CHH for lunch and finish about 1:00, go back to Peter Pan where the standby wait is at 45 minutes, push past 2/3 of the people standing in the queue for an overall 15 minute wait time. This is GENIUS!!
Not fair, you say? Then how is it fair for dad to make a FP run & catch up to his family in line later? Or for Junior to go potty and get a Coke while the rest of the family enters the queue & then push his way through later?
I have absolutely ZERO problem with someone who is already in the line, exits it for whatever reason up to and including sudden-onset hair fires, and then rejoins the line. But just hardcore walking-up-and-skipping-the-line is gross. Even if you think you have a reason.
Note: I'm exempting any queues that Disney has already set up to accomodate "placeholders" like the Merida M&G, etc. They've clearly thought of a better way to run those lines.
If and when Disney sets up the rest of the ride lines so that no one has to wait, and we all take a virtual number and come back when it's our time to ride, then I'm all for that. Bring it on. But right now? Right now, you are supposed to wait your turn. All of you. Not just the ones who feel like holding a place for their entire family who are roaming the park elsewhere, plus those of us schmucks who are flying solo.
Now, am I going to do anything about it other than give you stinkeye and possibly stick pins in a little you-shaped voodoo doll later that night? Nope. But rest assured that, as you squeeze your sweaty body past me in the narrow queue with that ice cold Coke and the look of someone who has recently peed, I'm thinking really bad things in your direction. REALLY bad.
ETA: clearly this entire post is tongue-in-cheek. Evidence: a) I would NEVER show up at a CS restaurant at 12:30 haha what am I crazy?!? and b) I'm not getting in a 45 minute standby queue for anything other than solid-gold bars. But I absolutely do have the voodoo doll of you so watch out. Just sayin'. *eyebrow waggle*
I'm not even meaning you personally but is it really THAT much of a big deal? I never realized people cared this much about what other people are doing. I'm not saying 50 people should be able to jump in front of you BUT 1 or 2 people? It's not even holding you up, except for perhaps 60 seconds or less!
I've done this and cannot see the big deal. Never for a ride but for a character meet and greet and only did this once. There was NO way I was going to lose my place in the Belle and Beast line at EPCOT! My sister waited, I went and came back. 
but I actually agree with you!
