Recently took a flight out of PVG.

There was only a J and Y queue, so I joined the J queue like a normal person; at this point I'm pretty much in the front, so it's all good for me. After the line started to get long, but the boarding process did not start yet (it was slightly delayed), this late arriving DYKWIA guy comes up and decides he's going to start creating his own line. I'm looking at him like are you on standby and the GA comes over and before she can say anything, he pulls the, "I'm a DM" card and she basically just backs off. Now you can imagine all the J passengers are trying to move to the new line, because they think that's the new J line. More confusion when they're told DMs have priority for them (paying premium passengers), thus forcing the GA to put out new signs that read "First Class and Diamond."

Anyways all this time, I'm still standing in the original J queue like ... assert your rights as GAs! But sadly there are are now some 35 DMs (!!) in the new queue.

In the end, the DYKWIA DM won.
