I can see the frustration from both sides. I would guess that whilst a patient is waiting in an area then should something have happened people were there to react and who had an idea of what had happened in the first place. Even with a porter, s/he has an idea of why they are being shipped to the Ward. If the pt. makes their own way and collapses en route then things become far more complicated. As per, not enough staff... well, not in the right places anyway ;0)
