I mean, that sounds very holistic in theory, but in practice just doesn't work out.

A few days ago I suddenly had my french press for coffee suddenly shatter and almost blast hot coffee over my upper body.

How am I supposed to start that call with "Hi, I'm jorvi and I made a mistake"..?

It's not like that is a unique situation either. And you can guarantee that if you tell customer service "I made a mistake", and it is clear they delivered a broken service / product (but often want to duck responsibilities), there is no way in hell they will not take the freebie you just gave them by admitting fault.
