I think a lot of the problem is the demands made on it. My mum would only take us to the doctors if our arm was hanging off. These days people live at the doctors or A&E. They also expect everything to be covered. I've heard people on here moaning about not getting free paracetamol and gluten free bread. FGS it's on its knees people!
People being late for/missing appointments also gets my goat. Someone was complaining about her appointment being given away for a routine thing for her child when she was ten minutes late. She was given another appointment at another surgery a little further away. All this helps clog up the system.
When I was pregnant I still paid for my prescriptions, even though I could have got them for free, because I could afford them more than someone on a low income. I'd be the same as a pensioner, as I don't need free prescriptions. Just because you can get something for free, doesn't mean you should (people on low incomes are not included in this, obviously)
I'd be happy when in hospital to pay for meals etc. Why do people whinge about that? When you're at home you have to pay for food, why not in hospital? People on benefits or pensioners could, however, be covered. People also moan like stink about paying for parking, when it all helps to cover the costs of the service. It's a fraction of what it costs to treat you or your loved ones and you have to pay anywhere else -shopping centres etc-, so why not suck it up?
People are so wasteful of services. I know people who go to the doctors and get a prescription from the doctors but have no intention of actually taking the medication, so it rots in the drawer (they tell me they don't like the idea of taking them). Why get the bloody tablets in the first place. Then also people don't take back items like crutches? There often used for a couple of weeks and people don't return them, despite them being reusable. I returned some and the staff were amazed! I've often seem them in rubbish tips etc. Why not take them back rather than dumping them?
We could all help preserve our NHS by just being a bit less wasteful of it and less selfish/entitled.
