It's a while since I've been through walk-in A&E up there, but the basic layout has a waiting room for walk-ins at one end for triage and minor treatment, the main A&E bay in the middle with bays down each side (10-12 total?) and a central area which is both workspace for the medics and an overflow if the bays are full, and a back entrance which lets the ambulances unload directly into the treatment area. When I got there all the bays are full and there were about 8 people waiting on trolleys, so it took a little while to get me into a bay - but only a little, and I'd already had IV morphine by then.

I just had a check on the web and the A&E department is actually catching serious criticism for its standards (particularly waiting time*). In fact there were major news stories speculating Medway-Maritime is the worst hospital in the country after it's latest assessment came out last month, but for me it got everything right.

* OTOH, as the senior volunteer in the bed next to me pointed out yesterday, we've gone from having three hospitals for a city of 250k, to 1 emergency hospital and one that's used for a limited amount of rehab work (mostly because the building is an architecturally protected Victorian pile and they can't shut it), while population is up to 270k. There's clearly internal management issues, but the main problem is systematic under-resourcing over the last 30 years.
