No, I'm sure we can behave ourselves.

When I referred to the poking in of noses, I was thinking of stuff like ID cards and other ways those in power keep tabs on us, not anything health related in particular.
Indeed they do, but we are talking about the actions of one local council here rather than national Government policy. I'm certain that there are better uses for money and time than daft schemes like this – as mentioned in the article
scotthayes linked to in the opening post and by several others in this thread, all people are going to do is shake the salt pot for longer to end up with exactly the same amount on their food.
Let's be honest though – how many times a week would the average person be visiting the chippie to use these new style shakers? Once, twice at most maybe? The amount of salt that is being reduced from their diet would therefore be tiny – and of course it wouldn't affect those who don't go in there in the first place.
Perhaps the money spent on this scheme would be better spent going towards educating the public on the dangers of too much salt in ones diet, which as you rightly say can lead to serious (and costly to treat) health problems in the long term?
