@Robert, really? I pretty much don’t care how much petrol / diesel is in the car when I collect it as the very first thing I do is brim it anyway, as long as I’ve got enough to pull away from the forecourt. Its a nice goodwill gesture if they give a tank of fuel, no big deal if they don’t.
But adding a £20 “surcharge” for fuel is something I’ve never, ever encountered – for context, many members of my family and my wife’s family have worked or still work in vehicle repairs or sales, and this is the first I’ve ever heard of a customer getting charged for what amounts to a quarter tank of petrol / diesel.
I’d like to know if that is an Arnold Clark policy or just the individual salesman trying to wangle an extra few celebratory whisky chasers whilst basking in his guile.
