So sophie's mum doesn't work either? She must go shopping to the supermarket as well as Dave so they could bring it home to sophie regardless. Dave was over the moon he no longer had to work. So was sophie until they realised babies are expensive.
There's more risk working in a supermarket than most jobs. And a lot more working there than a quick visit!
Dunno why they aren't buying baby stuff with his furlough wage though!
