Yup! Just saw that on Steven Colbert or Jon Stewart...poor guy...
I noticed the people working at the airport and on the plane on my most recent trip came in either one of two personality packages: Very happy or VERY annoyed.
On my way to Brazil, the guy who was checking tickets and passports before going through to the metal detectors was particularly PO'd that day. He even said that he was really cranky to all the people in line within earshot.
I understand that he was in no mood...and the people after him weren't much better. Someone else working in the metal detector area had a water bottle, held it up above their head, and screamed out to everyone still waiting in line "See this?! YOU CANNOT have something like
this with you!"
*sigh* While on the plane, RIGHT before we are about to take off, the people in front of me always seem to INSIST on putting their chairs back even though they will have to put it in an upright position VERY soon. Which is extremely annoying. Since I end up not having any room because if I did the same thing it would probably annoy the person sitting behind me as much as it was annoying me.
Also on the way back, one female flight attendant looked and sounded like she was gonna do what this guy did any minute...she looked pissed at everyone. I barely bug the flight attendants on the plane, so it keeps slipping my mind that other people might not be as unbothersome as I am to them...so all I could think of was "Why is everyone that works for this place so GRUMPY?!" But yeah, it finally hit me now. It's gotta suck to do this with such rude people all the time.

We need you to keep your cool! Stay strong.
