Shopping in Habitat, a very very posh couple were conversing with each other across the shop, shouting "Darling" before each product analysis, which included this from the man:
"Darling. Look at this. A decanter dryer. What stage do you need to have reached in life where you need a special device to dry your decanters?"
I'm not sure myself, but clearly neither myself and the other half, nor the Darlings have reached this stage as they left empty-handed and we bought a linen bin.
If you have reached that stage in life (I suspect I never will), then Habitat in the Westfield Centre has plenty of Decanter Dryers in stock.
