Cost to you is not necessarily the true cost. It depends on how the ER is being funded. Since you're in the EU, I assume you've got socialized health care. That means everyone has health insurance with a co-pay. A co-pay is intended to discourage use, not cover costs. The rest of the cost of the ER still exists, it just isn't directly funded by people attending the ER.
