I'm not sure it's as simple as he implies, though. The times I've been to emergency rooms (from a child to recently), there were an awful lot of people there for serious things, not free pregnancy tests and the like.

No doubt that some people do go to them because they won't be turned away, though.

Perhaps if there were as many walk-in clinics as Starbucks then ERs wouldn't be as popular (and expensive).

Cheers,
Scott.
