I'm not trying to make excuses for people who do these things, but if you think about it, you can almost see why people would do/say things to the staff. Either they or thier loved one is sick, to them, it is the most critical case around. They are desperate, maybe afraid of what is going on, and they are not thinking straight. A person without such a personal concection to those who are sick can see that there is a certain level of traige that needs to happen, but those in need of help are blind to the plight of others. It's a shame, really.
I can recall the early 90s when Daddy was quite ill. I took him to the ER/clinic at Madigan (millitary hospital where patients are seen in much the same fashion as the NHS). There we sat, Daddy in a wheelchair barely able to breath, surrounded by folks with colds and coughs, and banged-up knees. Daddy goes into convultions, litterally, and I scream for help. The Drs all RUN to Daddy, wheel him into the back room, and some private, in camo and all, there for what looks like a broken finger or something, starts freaking out on the Dr, saying he'd been there for an hour, and "that old man" has only been here 5 minutes. He was pissed! The MPs cuffed him, and I imagine he had KP for a while.
Crazy!
