I don't fly much, so I've never seen anything like what I witnessed this weekend...
After the drink service was over on our flight, a passenger in the middle of the plane started having chest pains. They did the whole, "Are there any doctors or nurses onboard?" query over the PA, all of the flight attendants are huddled around trying to help - scary, right? Then a nurse steps forward, and one flight attendant is heading to the back of the plane to get the medical kit - until she's waylaid by the woman in front of me, who stops her to ask, "Can I get some coffee, please?" The flight attendant is flustered and demures - "After we've dealt with this MEDICAL EMERGENCY, I'll see what I can do," and tries to continue on, but crazy passenger lady interrupts her to ask, "Well, can I just go pour some myself while you're busy?" FA quickly says, "No," and hustles away, coming back with the stethoscope and blood pressure cuff the nurse needs.
Wouldn't you know it? While all of the attendents are still distracted, the passenger goes back to the galley and tries to pour herself some coffee anyway, but for some reason, the carafe wouldn't come out of the machine. (Security, maybe? Probably best not to let random crazy passengers have access to boiling hot liquids.) This lady had loudly been discussing Xanax with my uncomfortable husband before the plane took off - I was sure she was going to pull a Kristen Wiig-in-Bridesmaids freak-out, and we'd have to land the plane early so that she could be escorted off by air marshalls. But once the stricken passenger was somewhat settled (laid out in the aisle, not out of the woods but nothing else left to do), the flight attendant actually did ask, "What was it you wanted again? Coffee? Okay, I'll get you some now."
It wasn't just the complete self-centeredness, it was the lack of empathy, too. When the incident first started, the chestpains guy's companion was crying and near-to-panic, and nutty Coffee Xanax women was chatting and laughing loudly to/at the poor person next to her. I'm sure she was a nervous flyer and on medication, but if you're that myopic that you can't see how anyone else might be going through something, maybe it's best to just take the train.
