I completely understand that once it became clear that restrictions and isolation are going to be necessary, people felt the need to stock up with enough food for a few weeks. I'm not going to criticise people for that, it's a normal survival instinct.
I did though, think that after the initial "panic", things would return to normal quite quickly.
I usually have a fairly well stocked store cupboard and was ill last week so I haven't been to a supermarket for two weeks. Just picked up a few fresh bits at the convienice store. I was rather optimistically hoping to do my usual weekly shop this week!
