Oh-So-Very-English Story Starter

Every once in a while, I pull a random picture out of iPhoto and use it as a story starter.  Here's one for today:

This shows a picnic meal of a scone with clotted cream and jam, accompanied by ginger beer.  (That's non-alcoholic, if you're curious.)  It just doesn't get any more stereotypically English than this snack -- unless it's tea and biscuits (cookies, that is) with the Queen.
The real story here is that I walked from Cambridge to Granchester one hot and sticky summer day in 2007, accompanied by a die-hard, born-again American Baptist fellow whose name I can no longer recall.  My enjoyment of the outing was rather diminished by the humidity and by his refusal to discuss anything other than his own narrow outlook on life.
However, the photo is a great set up for fiction.
What would you do with it?  Who's picnicking in the park?  Why?  When?
Feel free to share your ideas or link to your own post if you write something about this.
Have fun.
