That's exactly what I did in 2013 and it was the best, most customer focussed service any of my bikes have ever had.
And the other Costas, the service manager, was the embodiment of what old-fashioned service used to be in the UK. He assured me that when they all went on the BMW corporate training events they were all told that customers were not their 'friends' but were fee-paying members of the public.
Costas assured me, with a glint in his eye, that I was now a new-found 'friend' along with all his regular 'friends'.
Oh, and the food, the drink, the weather and the social life were pretty spot on too...
