For an instance, i know its basic courtesy to give in to the
elderly but i think some are abusing their rights. . .
I've experience an elderly pushing her way through and board the
train even though the passengers have not get out which is kinda
rude.
The worst i ever felt was when this old lady (shorter than me)
slip through to my front when the train was braking and getting
ready to open the doors though the gap between me and the door was
very short.
imagine this sort of things happening in britain or america, i
bet the get into some quarrell

i think there was someone who was sincerely enough to ask a
middle-age lady to take his seat, but when he addressed her
"ah-m", i think the lady was not very happy so die die don't
want to sit
