(UK resident) I am happy for it to work automatically. Just like I am happy that if I need to see a doctor or go to A&E it is paid for automatically.
Here you don't pay any income tax on the first ~£10k/a that you earn. To be paying enough tax to be worth complaining about you must be taking home enough money that I have little sympathy for you.
But maybe some people like spending their life being annoyed about numbers.
