I am unfortunately very familiar with the policies of my local hospitals due to having multiple chronic conditions. They only partially reduce parking prices if you have a visit that lasts 4 hours or longer. At least, that's the case for the hospital which I regularly have appointments which last that long. The other hospitals won't provide any parking validation. Insult added to injury.

I remember when I lived in a smaller town and had never experienced having to pay for parking at a hospital. I read on reddit somebody commenting from the UK about having to pay for parking at hospitals and I thought it was absolutely barbaric. Everybody downvoted me because apparently it's normal. Now I know better. It's normal. Barbaric, but normal.
