I'm genuinely confused. People were queuing at some local supermarkets from yesterday afternoon, even before announcement. All delivery slots got booked up in my local area after the announcement. Supermarkets are still open. We can still drive to Sainsburys or Tesco or wherever and do a big shop like before, or walk/bus to local shop for those who don't drive.
My understanding is that in England stores will not cordon off non essentials anyway like in Wales. I plan to do one big shop a week as always at my local supermarket, wearing a mask and social distancing like I have been doing for the last few months. This is still allowed isn't it?
So why are people panic buying?
