hong kong is different. their last time dd bus lower deck is ALL
standee. so i would expect in their case, they move into the rear
without much fuss. cuz u stand at door or at rear also must
stand.
in japan they have many "conductors" blow whistles n stuff n
squeeze ppl into rain
and if u want to squeeze ur way into the crowded train, u do the
following:
juz do a slicing motion with ur hand, then the people will
automatic suddenly part. then what u do is u bow to say thanks n
move in quick
