As an airline employee I am taking another stance. The place for that article was not in front of the customers but perhaps in a back room. I agree it was in poor taste but I think many on this post are being way too sensitive. And for those other airline employees - you have never done ANYTHING wrong ??? You are perfect and have never gotten any complaints about your "service" with a customer? Living in an imperfect world I would find that extremely hard to believe, not to mention millions of other employees who deal with the public other than airline employees. In other words, you think that employees of Macys, McDonald's, Hertz, movie theaters, restaurants, toll booths, etc., etc., couldn't or shouldn't have anything negative to say about the customer (out of earshot of course).
Get real, being politically correct 100% of the time is not possible in an imperfect world. Wake up and slap that cemented phoney smile off your face. I may not be rude to a customer but if I want to call him/her an a--hole after they walk away when they have been rude,dumb and nasty to me, I am not going to worry about some holier than thou, "sinless" coworker who actually believes that people like this don't exist. I keep an eye out for those like you who are ready to rat out/write letters in an instant with no real facts.
