Still, there are shortages. For example, my local supermarket has for a month or so had signs explaining that "Supply difficulties" may mean some items aren't in stock, e.g. most of the Italian ready meals section (I like Italian and I'm lazy) is replaced by an incongruous display of Italian wine, even though the wine section is actually on the far side of the store.

They are clearly struggling. And even if Brexit is only 10% of the problem, they run into the fact that it's key to central government policy to portray Brexit as successful, and so you mustn't mention that element.

We don’t need to rely on photographs to physically see the sparse shelves with our own eyes

I dunno, this site probably disproportionately represents the kind of demographic who just orders all their groceries on Amazon Fresh and hasn't set foot in a grocery store in months anyways. Maybe some people do need photos.

True.

That said, my local large Tesco had a small few aisles completely empty - yoghurts I think, and some fruit and veg.

Clearly not an apocalyptic situation, and much better than the Great Toilet Tissue Shortage, but unsettling nonetheless.
