I trust the Good Lady applauded your effort after she stifled her sobs. Brexit wine shopping sounds a bit like buying food with an impending hurricane - there will be that shelf with the lone can of low-salt corn dented through its midsection offering itself up like a can of caviar.
Best wishes next weekend for the Good Lady's wine options.
She appreciated the effort but perhaps more so when I went further afield the next day and returned victorious!! There ain't no crisis! At least for a short while. No more dented cans of low salt corn wine :OD
