We've noticed the trend of anonymously posting work grievances through the animated site xtranormal.com. There have been ones made by the camera crew, locations, accounting, even the Teamsters have one up!

This passive aggressiveness isn't limited to film crew; my eye doctor posted Optometrist vs. Patient on his Facebook page. Everybody in the world hates dealing with stupid people at work.
Here are our PA relevant favorites thus far:
...in which a PA tries to get an unruly Extra to come on set. As lowly as the PAs are on the crew, Extras get treated like stray dogs.
"You look like a clown prostitute. I don't care enough to change it, just get to set!"
... in which the Key Set PA annoys the crap of the Production Coordinator. Somehow giving her a British accent makes this even more realistic.
