Another thing that occurs to me is that it's the Xmas Eve night shift. I've been in A&E on Xmas eve (escorting a colleague who'd been attacked in the pub I was working in) and it was CARNAGE.
And yet EP and DU spent 30mins talking about his hurty feelings and with the walk to the car I am prepared to bet EP was out of action for at least an hour, and sent DU home. So that's one doctor down, and the head of A&E AWOL for an hour, on one of the busiest nights of the year. So much for a focus on patients.
