When I had my children around 40 years ago a lot of the staff I encountered were unhelpful and some of them were downright unpleasant.
Cleanliness on the wards was pretty indifferent even then. And tbh the staff could be very impatient and resentful if asked about anything.
On the maternity ward there were so many complaints by patients about the night staff, all agency staff, that for a brief period the hospital tried to stop using agency staff, which didn't really work as that was only night staff they could get.
I remember about 35 years ago when I was having an operation. The surgeon came to explain to me about the procedure, followed around by a group of students.
After about 5 minutes of his rather patronising talk about what was going to happen during the operation I realised that he was describing a completely different procedure. Having pointed that out to him and the fact that the file he was holding wasn't mine - mine was overflowing and this was a very thin file - I didn't even get an acknowledgement of his error.
Thankfully, he did the right operation on me in the end but I think the NHS has been in a sorry state for quite a number of years.
I also think it very much depends on the part of the country you're in as to the length of waiting lists and quality of service. I know someone who lives in a rather nice part of London who has had several operations recently, often waiting a matter of weeks rather than years to be treated.
