Can I suggest you do something?
Which is what I've been doing, (I may get a flaming here, maybe not).
Why not buy your food from small suppliers online? There's lots of next-day availability, it helps support small businesses, you can stay out of the supermarket and thereby ease the situation for others, and you get loads of great things to eat and drink?
What's not to like?
It might seem a bit 'let them eat cake', but I like eating nice food and I want all the small producers to still exist when this is all over. So instead of hitting the already overburdened supermarkets, get online, look for local and artisan producers and suppliers, and spend some money with them.
