It certainly will be interesting to see how it pans out. Where I live in France supermarkets are crap for choice and my meat comes from local farmers anyway
Saying that, if my old home (Taunton) is typical of the UK as a whole then people are massively oversubscribed with supermarkets -quite frankly anyone who can't find what they want or define it as a 'shortage' from that does not know the meaning of the word. I mean, Taunton (60k residents) has a large ASDA, LIDL, ALDI, Morrisons, Tesco (and 4 Express), One out of town Sainsburys, one medium size one in the town centre, plus loads of independents. They may have a narrower range but the way people talk is as if there is nothing at all.
It may be in the future more supermarkets go the way of ALDI / LIDL where you have one or two lines of things...I mean, how many types of beans can you stock and make money on? And if it really goes to the wall make your own bacon (if you can source a chunk of pig) and you can then make sausages too.
