Have you really thought through the implications of this? That you give half as careful a work-up to people who behave in a civilized manner, because you've spent your time giving double (read: thorough) care to people who are being belligerent and making false accusations against the hospital staff? Gee, maybe I should keep that in mind next time I land in an ER. To get a really thorough work-up, I should scream and yell, be disruptive, make false accusations against the staff . . . even though I'd much rather be courteous and civilized.
While I certainly don't advocate a transplant for a condemned murderer, I think it's a very slippery slope to decide who is worthy of emergency care and who should be denied care. And we all know those kind of lists have errors - I wouldn't want to live with the consequences of being misled by an error on the list. And finally, some people who have scammed, mistreated ER personnel, and are responsible for their own illness have also gone on to redeem themselves later in life. You may want to judge who deserves care, but I certainly don't.
I just reread your post - I didn’t say I gave them “double care.” I do think about it more, though. As in stopping to ask myself “is there something more I would do if I didn’t dislike this person?”
