The staff coming back to LA are way more nicer than the ones from LA going to Seoul. They are not friendly at all. I asked for a simple additional water while she's passing the nourishments, she gave me that sharp look, and said "WAIT", then shortly after she gave me the water and she just dropped the cup on the table without saying anything. For a moment, I thought to myself, "does she talk"? she's is so rude. Overall, i didn't see anyone smiling.But I want to give a kudos to the group from Seoul to Manila and the entire group coming from Manila all the way to LA. The only bad experience I have encountered was from the group going from LA to Seoul on Feb 25th, they are not compassionate at all. Its not even busy because there were a lot of empty seats, the stewardee assigned to my seat was very rude.
