"Why book an operation!"

I took my 82 year old father for his planned operation which he has been waiting for a number of weeks. We got there early for our 11 am slot and waited. one hour 40 minutes later we got in,he signed the consent form and got changed. The wait began again. After being moved several times and told to get ready, the manager of that department came to see us just after 5 pm to announce that it had been cancelled! In her words " a piece of kit had not turned up" Not sure where it was coming from as it had 4 weeks to turn up. My father had not eaten or drank since 6 am and has Dementia. Is this the way we treat our old people who have worked and paid taxes all their life? My parents brought me up better to say what I really want too!
