Aside from my friend's stupid "wait till tomorrow to go to the doctor's office" instead of calling 118, here's a telling story about our national health system.

The national health here does have serious flaws - far worse in some parts of the country than others, long waits for elective procedures and diagnostic tests, and a really stupid one-size-fits-all attitude about durable medical equipment (which can be fought and won in the same way Burgerman has done with WCS in the U.K. or I've done with Blue Cross in the U.S., but it's a draining and wasteful process). Nevertheless, it works and in general is equitable - you get good care whether rich or poor.
P.S. The "bill" Roger got was as "high" as it was only because he has substantial income. It's an income-adjusted co-pay.
