Yes sometimes it's a person literally on the doorstep of the ER in front of the doors. One time a news report said the person was in a passenger seat of a car. But usually right there at the ER in some state of distress.

I can understand some concerns of staff but to flat out refuse seems to go against the ethics of being in the medical trade.

I also suspect it's government bureaucracy and union rules, paperwork trumps life I guess.
