Their custom officers have quite bad attitudes especially those
at the second links. It quite contridict the badge that all custom
officers wear, service with a smile.

Actually there seems to be an increase in the number of people
begging, be it the Fake Rolex sellers, the beggers or the 'car
cleaners' ( who uses a dirty rag to clean).
If one is to use Singapore as a benchmark, for crime and corruption
Malaysia will fare quite badly, however when compare to the region
it is quite safe, therefore to make extreme statements like I WILL
NOT GO TO MALAYSIA is quite unfair to them.
But for those who go in for petrol and shopping it may not be as
worth as one will think, being that one will end up spending more
sub consciously, maybe on food or other stuff. If added to the
total bill it may be just a few dollars in saving. Of course, to
add to the point the jams that one will need to bare with.
Of course, it is just my opinion.
