Re: "how we label our food"
My local market never stopped selling in pounds. Unlike the 'metric martyrs' (AKA illiterates & cretins), they read the regulations, sought advice, bought dual standard scales then promptly added the lb prices below the metric ones and carried on as normal.
Today it's still possible to buy in metric or imperial but few do it. The new measure is 'the bowl' and doesn't get weighed at all!
