Bumped into this online. Interesting theory - Makes as much sense as dumping the pint and adopting the litre*.
* I'm all for it - when you are really thirsty there are few things in life as satisfying as a litre of cool crisp Czech Lager, however, despite the aforementioned beverages qualities, I do respect and hold our heritage in high regard, and perhaps a pint would be best preserved as an oversized glass in which beer is served, with a lined 500ml, thus accomodating a healthy flavoursome head above the metric half litre.
