Where abroad? France's service is excellent, far better than ours.
My family use private medicine as and when. We have access to a private doctor in London. A visit doesn't cost much. For minor matters it's a quick,efficient, service; for serious matters, we'd use the NHS. I remember the daughter, then age about 10, had a mysterious skin rash, which the GP couldn't identify. He rang a specialist, we went straight round to him. He said that classic thing of skin specialists "It's not dangerous, it'll come and go, it's never going to be unsightly,just pinhead marks, and there's no cure; it's in the body for life". Whole thing cost about £100 or so.
That is what the NHS should be like; France's service is like that now.
