Nothing is 100% great 100% of the time..Then again some people are ungrateful and always find something to moan about
I'm not sure your virtue signalling applies to cases where a patient has died or been permanently injured, or continues to suffer miserably due to incompetence or malpractice. I would argue that for some parts of the NHS the care and treatment on offer is comparable with that of the third world. I would not be so eager to count out the experiences of others just because they are contrary to your own.
