The ROH also has a system of moving you to a secondary waiting area[1] near the conslutation rooms, which has approximately 1 chair per room. (Which isn't enough anyway, as many patients are accompanied.) If we discount the wheelchair users, who come with their own seating, I'd say about 50% of patients have an impairment that means they Really Need To Sit Down, trending to about 90% for the hip and knee clinics. Plus there's the occasional wobbly relative, especially amongst the hip replacement demographic.
Seating is routinely re-allocated on the fly using a cross between musical chairs and a joint[2] version of scissors-paper-stone[3]. Which - with my compsci hat on - I note, is as good a cache invalidation algorithm as any. But that doesn't make the standing around any more fun.
[1] Which may just be a corridor.
[2] In the bones sense. That orthopods thought having something called a "joint list" (in the combined sense) was a good idea is a matter for the grammar thread.
[3] Hip-knee-ankle?
