She’s throwing out soy sauce, jars of pickles, packets of cheddar biscuits, unopened tins
They don’t normally eat them, so are of no use.
I think shes confused and got wrapped up in the panic buying frenzy.
Normal people buy standard cupboard items you use and know will keep. Or freezer food you have room for. She got carried away in a literal panic!
Sad but I bet she wasn’t the only one.
