You can never please all of the folks all of the time, if you work with the public someone will always complain about something. I suspect your profession cops for a lot of displaced anger and anxiety,from patients relatives. Say little old lady is found by her son/daughter, she is on the floor having being there all night, she has a broken leg and is cold. son/daughter is probably terrified mum will die and, its all there fault because they didn't call round last night, fix the loose stair carpet, get another handrail put in or whatever, the list is endless, they are distressed, they will go over the incident with a fine tooth comb, looking for somewhere to dump their angst, because that is easier than facing how they really feel. I think you will always be in the firing line Of course you get complaints from absolute Muppet's (well we can see that!) and you have my admiration in your ability to go from a 'desperate' job to a 'rubbish' job without doing something regrettable with an oxygen bottle to the latter!
