You'd better not be desperate.

We missed a turn en route to the campsite. (Sam Sam was on strike)
Due to unexpected lack of Satnav and the nature of the route we had to go on a mile or three, turn about and retrace "steps"
Being in need of both relief and refreshment, but not necessarily in that order, we stopped at a well-known Coffee brand Emporium.
Fortunately, on a wander back to the van I came back by a different route so was aware of this state of affairs.
NEVER met its like before in a "Cheepas".
