Smart. Or rather common sense, which in many cases is also in short supply at the park, as evidenced by the ignorant comments you heard from the "sheep".
This is just was I was thinking. Smart on your part. I've done this many times whether it was at a turnstile or in line for food. It also happens many times when I would go to POTC here at WDW and people would always use the right side of the line and follow all the other people even though the left side was also open.
I alway keep a role of nickels in my pocket (insert unflattering comment here). When I see a CM about to open a register I rip open the wrapping and toss the nickels to distract the people already in line. They scurry to pick up the nickels while I jump to the newly opened register and place my order. You see, people get a couple of nickels and aren't that mad when you jump to the front - they feel they got something out of the deal.
Squirt guns work great too! It's fun for the whole family.
I have obtained my delicate figure through many many pectoral exercises.
Helps to have that short hair, too.
Back to topic: smart, lucky, quick.
This is why I prefer one line, with new servicers taking the next in line. It's easier to take a servicer out of service this way as well. AKA, "The bank line method."
"Here You Leave the World of California Today and Enter the World of, um, er, California Today."
Whenever I'm in this situation, inevitably, just as I get to the empty queue, someone from the other line rudely yells that "there's only one line!!!" and by then, 4 more people have joined the original queue and I find myself even further back in the line than before!
