Today I took my Prius to the dealer for the (non-urgent) steering column recall which is under way. It took about 2 hours, during which time I lounged around their comfy reception area, swigged their rather good machine-made coffee and read a fun book. IOW, no real pain.
When the job was done, they said it was their habit to recompense for the hassle: (a) a bottle of champagne (75cl, with Toyota (GB) Ltd tag, but no Toyota Part Number); (b) top up the petrol tank; and (c) vacuum the interior and wash the exterior.
Sadly: (a) I'm not a big fan of champagne; (b) I filled the tank just 22 miles earlier, expecting to run dry on the way there; and (c) the car wasn't too dirty and they made the windscreen smeary whereas it had been nice and shiny.
However, all were pleasant and well-intended courtesies. What of dealers elsewhere?
