Wasn't an attack at all! Maybe a bit smug...but certainly not uncivil.
There is nothing left to explain...I look at queues as basically all the same. A way to wait for...something. My DMV license, a Dole Whip, meat at a deli counter, a concert, an iPhone, a ride on Peter Pan, a banking transaction, an elevator at a tourist destination etc etc etc.
And in almost all except Peter Pan, no one would ever expect every person in the party to be present 100% of the time in the queue.
It seems you think each of these other queues is somehow unique and that there should be one set of accepted rules for all of them and another set of accepted rules for ride queues. And you are not alone! So many agree with you....
But there is nothing left to explain or argue about. you see it your way I see it mine.
I even do it your way!
What's more civil than that?
