Which Comes First - Cream or Jam?

I'm being side-tracked at the moment by sun and beaches and cream teas.  Which leads into the riveting discussion about the order you put your strawberry jam and clotted cream on your scone.  Is it jam first, or cream?  

I've always been a cream first person - the cream = butter, and that comes first - but this afternoon I got seduced into trying the jam before the cream.  It looked aesthetically pleasing (and tasted delicious).  Perhaps there isn't a right, or a wrong way, only the way you've always done it.  

Bit like writing a novel.  To plan, or not to plan?  Does it matter how you write it, so long as you get it written?  The answer has to be, no one will care, so long as your work is good.  How you pronounce scone, on the other hand - now that does matter.
