I have been that parent with the small person about to have an accident, so yeah I've dragged my kid back and forth through a line of people, WHEN the CM was nice enough to select a "holding point" we could rejoin the line at. Otherwise we went to the end of the line. Life lessons you have to teach!
I also have "cut in line" at the buses. End of the night EPCOT, total insanity, my DH and DD kept heading for the buses and I paused for a moment to snag a quick photo of the bus stop numbers. In less than a second, they were GONE. And without a cell phone, all I could do was run screaming through the crowds to our resort bus stop, yelling, "We have to be on #_______!" I was terrified to get separated from DH as he had all the ID, the bags, the phone, our kid....
When I saw them waiting at the wrong bus stop, I ran through everyone, screaming about the correct bus stop. Perfect timing for OUR bus to turn the corner, pull in, and stop! Except that we got all sorts of dirty looks for climbing over the railings (no room to maneuver back out with people pushing like a mosh pit!!!) and leaping into the correct resort "stall" ; which coincidentally put us on the first bus out... but anyone still giving me a dirty look at the bus stop did not realize my place on the bus, clinging to a child who was wrapped around my leg and a hand strap I'm sharing with DH, standing on one foot while I can feel the person behind me BREATHING because we are pushed up so tight against each other. Hot and humid and SQUEAKY ride back to the resort... squeaky from everyone's sweat trapped in an AC'd bus.... LOL ewwwwwwwwwwwww
I really wasn't very Joyful at the Sadness & Joy M&G though... there was serious placeholding going on there, and the CM's weren't doing anything about it. We had a 45-minute wait in line, and we just weren't moving. Finally we start the continuous shuffle... we are the party after the "next" one, I'm so relieved as I have to go to the bathroom and DD is exhausted... and suddenly the little old woman in front of us claps her hands and hollers.... for the 8 or so children that were literally crawling the carpet walls and eating things they found on the ground and running around like crazy animals. Admittedly I probably shouted, "WHAT ARE YOU DOING!!!!????" loudly enough for people in Norway to hear me! The CM's just rolled their eyes and smiled at me... "Next.... Next..... Next..." but in hindsight, they can't abandon their post, what exactly can they do? They can't take away FP+ hahahaha imagine that!
