Anything that is given to you free, there should be no
contention.
If you walk along the streets, some company gives you a free
umbrella on a rainy day. The umbrella breaks apart half way in the
rain. Can you raise an objection with the company? In the laws of
contract you have no case because there was no exchange of
consideration. If you think you deserve a better quality umbrella,
you purchase a better quality umbrella from the stores.
Likewise with the NHS, the healthcare is provided free, if you
think that you deserve better service or can't wait, you purchase
it from the open market. That's why some chose to go overseas for
treatment while others chose to wait in line.
Whereas in the case of Singapore, things are much different. You
pay for hospital fees much higher than a Hong Konger would pay in
their country and you get crappy service.
A few months ago, one of my family member had to be warded for a
minor procedure. There wasn't any beds available, just think about
it, I am paying for a service at above average rates (when compared
to a Hong Kong Hospital), yet I have to wait 12 hours to be
allocated a bed.
