Same with our local Mini Franchise.
You could hear a few ripe comments in the background re another car which was sort of funny.
Then he wanted to charge me £200+ for a new battery.
I asked and they said a video showing a problem had a far better chance of the customer saying "go ahead" than a phone call so it was worth it. It appears people trust their own eyes more than a service advisor.
Same experience with our Mini although it only happened the once.
Actually £200 fitted for battery is not too bad. The large stop/start AGM which I sourced and fitted still cost over £140 cheapest!
Our local "guvvy job" guy does servicing now for a pittance and even has access to the tablet thingy that's adds in fresh service history to onboard system.
