I think time is a valuable commodity, and many people I know that own expensive and fun cars have to work hard to do so. So wasting a whole day for a car service isn't ideal if you can avoid it.
For comparison, I go to Ian Allan early, drop the car, either do some work in their place or at a nearby coffee shop, they are typically late finishing, then I drive it home in traffic.
For my GR Yaris (while I had it), I paid £15 extra for the dealer to come pick up the car, they do the service, they drop it back home to me.
