gd.
i think the stewardess also dun wan work in SIA anymore le, so
might as well just sue the couple for some money 
but u think abt it, working in service line, there are bound to be
incidents like this. sometimes when pple hurl the meanest
abuse to u, u simply have to keep ur mouth shut with a smile.
Just not long ago, when i was in a macdonald, some idiots just
couldnt wait a bit longer for their food (peak hour ma, i can see
all the people all rushing like mad), and started scolding the
manager. That idiot was horribly rude. So rude that i was thinking
whether his parents taught him manners. Maybe he was brought up in
an uncivilised home or his parents was cave men and women.
How i wish a million hamburger could fly to him now and maybe
screw his arse.
