When I got bonked on the head and sent to the hospital several years ago, I definitely went for the banter/humour interactions; it made me feel a lot better to make the hospital techs who poked me crack up. I always appreciate health care people who can chat and laugh with me, rather than the ones who are OMG SERIOUS BUSINESS. I either don't often get the solicitous reaction, or I don't notice it when I do.
