Nit-picking session.

I'm never 100% sure how any conscientious vegetarian can use butter: bearing in mind that the cows are forced to have calves regularly to ensure milk - whence cometh butter. Or didn't they know that.
Anyway my usual grouse is more about the Brit concept of non-metrication. I've been this route before, but it'll probably annoy me for ever. You buy a bottle of liquid and 9 times out of ten it'll not be 450: 500: or 550mls, it will, in all probability be 568ml. WHY not 569?
That's 1.00130001825591 pint, whereas
568 = 0.99954026426952. Where's the difference? NEITHER is a pint!
You buy a jar of honey, jam, etc. NOT 450gms but 454gm =16.0144 oz.

Whilst wandering idly along with the Gaffer, shopping, I spotted this gem. Morrison's have, actually done the dirty deed and gone metric.
Not the 227gm = 8.00719 oz. Yer actual, genuine, metric amount 250gm.
How do you spell "Weigh Hay!!!"

:¬))

It's O.K. I haven't, really, flipped. I'm just rambling, coz it occupies the mind.

"It may be rubbish, but BY JINGO it's British rubbish!"
