Maybe I missed his point, but first of all, yes, hospitals do have waiting rooms - just (obviously?) they're not filled in the middle of the night, as only people with, well, emergencies tend to go to the hospital in the middle of the night. Secondly, e.g. going to the dentist is almost guaranteed to be an hour's wait (at least where I live), even if you have an appointment. Say, you do have an appointment for 1500, then what many people around here do is, check in at 1455, ask how long the wait might be, and then actually leave to do some shopping or similar and come back in whenever their wait is nearly over.

So really, I don't see how this could be superior to any other system.. And is he pleasantly surprised at the 250ish Euros or did he consider it too high? In case of the latter, I don't know why he doesn't have German insurance in the first place. I currently pay less than that amount per year (though that's the public health care kind, not the private one, which arguably would be more expensive, but also better), and IANAL, but I think if he lives here [in Germany] he is forced by law to have some kind of health insurance.

Don't want to come across as too negative, but I just thought I'd give you the other side of the story as well. (I currently live in Germany and I am covered under public health care.)
