This is odd. When I go to the doctor, even the emergency room, I am required to present a photo ID. There’s a sign to that effect right at check-in. However, it is against the law for them to ask if I’m a citizen. A nurse told me Hispanics often give a fake name, which to me means, no ID. I am also required to present a photo ID when receiving medicine. Someone else on the forum was complaining about having to present an ID to receive the Covid vaccine. (As Victor David Hansen has pointed out, the law is only enforced against citizens. It does not apply to illegals.)
As far as I know, the requirement for an ID occurred because a college girl had checked her friend, who had no insurance, into the hospital using her name and her insurance. The girl died and the wrong parents were notified. Apparently, it caused some significant legal action and the ID requirement has sense proliferated. (Much as HIPPA has proliferated to the point of stupidity.)
Fraudulently documented foreigners have more documents than citizens do, many in different names, different addresses.
Citizens have SS#’s and can be tracked down by collection agencies, illegal aliens are not. Even the payment for services doesn’t apply to them.
