Er, no. It was a joke (no doubt a poor one), but based on real
experience (and if you know anything about Korea, you'd know that
Koreans can be ... feisty).

Not while on duty as cabin crew. And the Koreans I met when I was there
were almost overbearingly polite (to western eyes).

[The experience in question involved airport staff, not cabin crew
(I imagine the standards are somewhat higher for the latter).]

I did have the interesting experience of travelling around Korea with a
Korean, and people were very nice and helpful to us -- and afterwards my
companion remarked "I've never been treated this politely in Korea
before!"
