After he was bonked in the head by a bag, Steven Slater stunned passengers by spewing profanity and ranting about quitting as the flight from Pittsburgh pulled up to the gate about noon.

“To the f—–g a–hole who told me to f–k off, it’s been a good 28 years,” Slater, 38, purred, cops said. “I’ve had it. That’s it,” he added, a passenger said.

The mad-as-hell steward grabbed a couple of brewskis and popped one open before activating the emergency exit, witnesses told airport employees.

After tossing his two carry-on bags on the slide, he followed them to the tarmac.

OK, first off, awesome. I bet if you work on airplanes you constantly think about busting out the emergency slide.

When I worked at the high school, my blaze-of-glory retirement plan included pulling the emergency shower in the chemistry room. I always wanted to see what that would look like and if it even was hooked up to anything. The chemistry teachers always gave kids a big speech about how they should never, ever pull that thing because it would flood the whole school. Unfortunately I left on good terms so I never got to find out if that was true.

Anyway, I have no idea what the background story is here or the nature of Slater’s fight with the passenger. But I know from experience that people can treat you awfully when you’re working a service job.

The article says the guy’s father recently died of Lou Gehrig’s disease and his mother has terminal cancer. Brutal.

I happened to endure some heavy stuff myself one summer when I was working at the deli. When you’ve got that going on, and someone treats you like you’re some sort of mindless machine that exists only for the purpose of serving them, it’s one of the worst feelings imaginable. You want to say, “dammit, you don’t know me, you jackass. You think I’m doing this for fun, you clown? You think I really care about your petty needs?”

You want to get on a loudspeaker, call the person a “f***ing a**hole” and storm out of there. I never did, but I get it. Good for Steven Slater for standing up for himself. Here’s hoping he lands on his feet.

Also, for what it’s worth, I fly JetBlue pretty frequently and Slater looks familiar. I’m pretty sure he was my flight attendant once. And furthermore, it’s amazing that the Daily News put three reporters on the flight-attendant meltdown story.
