By now you've probably heard the story about the 39 year-old Jet Blue flight attendant named Steven Slater who, after his flight landed in New York and arrived at its gate, got on the intercom and cursed at a passenger (who was prematurely grabbing his overhead baggage, apparently, and then became abusive after Slater told him not to) before opening the emergency door and sliding down the inflatable slide. He then ran across the tarmac to his car and fled home.
It seems that he was just really fed up with his job and quit spontaneously in an almost theatrical way. (That's his photo above.) What he allegedly said over the intercom tells the whole story. "To the passenger who called me a motherf**ker, f**k you… I've been in the business 28 years. I've had it. That's it."
An under-reported detail of the story I really loved is that he apparently grabbed two beers from the galley just before he launched himself down that inflatable slide. You can read more about the story HERE.
