Yes, I've waited inordinate periods of time in A&E departments, and yes, on occasion, I've suffered at the hands of a pompous consultant, a brusque junior doctor or a blithe nurse, but factoring in just how exhausted and hard-worked these people are, their behaviour was entirely understandable. Just think how rude the staff in shops can be, and then imagine what it would be like if they were about to cut you open, or deliver your child?
