There's a big difference between getting angry and acting like a dick.
+10000000000.
Here's my personal experience.
After getting my hard case luggage in NAIA(inbound from SG flight), I noticed that the corner of my luggage was cracked and shows a 1 inch hole.
My luggage was 2months old and it was my first time to use this bag. WAS very pissed.
Did I make a scene at NAIA? NO!!!
I walked to the airline counter and complained in a courteous manner. No cursing, no disrespectful/hurtful words came out of my mouth.
Followed procedure for filling a complaint.
After a couple of weeks, I received a check. Amount is based on price I declared.(book value of my bag)
Another recent incident last year.
I was in HKIA en route to Manila.
During the boarding process, the airline staff who checked my boarding pass ripped it in front of me and plainly said that they changed my seat. Felt like my BP rose to 240 and in an angry and loud voice i said " Why did you change my seat!!!???"
He responded with 1 word "BECAUSE" and pointed to the seat number on the new boarding pass. In a split second my anger was replaced with happiness and bliss.
They upgraded me to Business class.
YES, I get pissed and angry at Airports. It is normal. But at the end of the day, it is up to you how you will react to other people.
