What's in a "full service" seems to vary quite interstingly
From here where even the condition of the radiator cap is being checked

Who's full service doesn't seem a lot more than what would be in an MOT and some basic checks
If you're going to a main dealer or a brand specialist you'd expect it to be carried out as per the manufacturer's specification.
My point is if you don't know what you're asking for how do you know if it's been done.
It's a bit like going into a shop and asking for a "whatsit" and coming out with a unidentifiable object in a box!
