why do you know such things??

Just like what I was saying about the introduction of
double-deckers to feeder service 95 between Buona Vista and
NUS:
I've been at NUS over six years, and I take no.95 on a
near-daily basis....
.... and I don't give a flying freak about double deckers at
NUS, apart from the fact that the hordes of students now actually
all have a fighting chance of boarding the bus.
