The issue here, is mainly about the timing of the hikes. To say
the hike is badly timed, is an ultimate understatement, and the
governments line of "Better one big hike at once rather than many
small hikes" on exacerbates the feeling among Singaporeans that the
gov't doesn't understand, which face it, they don't...
As for the examples of poor service cited by Silkmagic, I think the
one that really deserves condemnation if the LRT fiasco. In other
countries, the level of breakdowns/disruptions etc would have
triggered a Board of Inquiry already. Alas, all we've gotten is
apologies and excuses....apologies are good, but what action has
been done to remedy the situation?
Buses getting into accidents? I think thats unavoidable, it might
not always be the bus drivers fault....
I can think up of a few other areas where services can be improved.
I have taken buses in Singapore several times when I'm back in
Singapore for school breaks, more than once I've boarded an aircon
bus and paid extra only to find the aircon not working. Once after
having the bus stuck in the heat at Orchard Road I finally snapped,
called SBS Customer Service and gave the chap at the other end a
piece of my mind. Basically questioned him on SBS policy on broken
down a/c in buses and when I found out that the bus driver in
question was violating policy, basically made some pretty nasty
remarks(no vulgar language don't misunderstand) to him about
getting better training and more rigid enforcement of the rules.
When he promised so, I snapped "Yes...please do" in a sarcastic
tone and hung up. Moral of the story, don't just gripe, do
something about it...
Another gripe I have is over what I feel are unnecessary frills
such as aircon-ed bus interchanges and TV Mobile. The latter is a
useless piece of crap if I ever saw one...takes up space which
someone can be confortable sitting on and more often than not can't
be heard over the bus engine. Maybe if they cut back on useless
crap like that we won't need to hear bloody SBS,TIB etc bleating
about 'increased operating costs'..altohugh I gotta admit, watching
Lisa Ang hosting Hey!Singapore on TV Mobile sure made the trip from
Eunos to Bt Timah a whole lot more bearable! 
Finally in their defence, I'd like to end by saying all things
considered the public transport system in SG is, to be honest,
pretty good, and not unafordable yet, although I don't know how
long I can say that. What must be addressed is wastage on
unnecessary luxuries, inefficiency and a tendency to raise fares as
the first and only resort to address rising costs rather than the 2
points I brought up.
If anyone is interested in hearing about my horror stories of
public transport in Melbourne do let me know...I'll be glad to tell
them here...
