In 50 odd years in using the NHS, never had any problems whatsoever. Not known any family member having a problem either.
What we suffer in the UK is that Labourites (Lefties) just forever and a day belittle our NHS. They just constantly call it shit and put the staff efforts down. I did post a stat years ago at how many million NHS interactions there are per day, and you will obviously will get the odd hiccup. The odd hiccup hits the headlines followed by the Lefty gang blaming Thatcher and the Tories. Nothings mentioned of the other umpteen million interactions.
Then the odd Yank picks up on this and the usual Neanderthal cliché blurts out.
Edit - There were an estimated 600 million patient contacts with GP, community, hospital, NHS 111 and ambulance services in 2023/24 (or the most recent year for which data was available). This is equivalent to 1.7 million interactions with patients every day.
