That's kind of their job. Triage patients, take care of urgent and immediate problems, send stable patients elsewhere. It's expensive because you've got to have a certain amount of medical professionals onsite to deal with unschedulable immediate problems, and more on-call in case the workload is higher than expected. And there's a legal obligation to stabilize patients without consideration of ability to pay, so you've got to bill at a multiple of the cost and hope some will subsidize those that can't/won't pay.
