I have to admit I found the British licensing hours appalling. Loved the pubs and the beer (great beer) but the trading hours were ridiculous. I reckon those restricted hours have actually created a culture of binge drinking. I have said this before but in my state a pub can trade 24/7 if it wishes and some (cbd based) do. Not much call for it in the suburbs though. There may well be a time of over-carousing but it will settle. Main thing is for the Parliamentarians not to lose their nerve because of the behaviour of a few boofheads who haven't worked out that you don't have to have fifteen pints in the next twenty minutes before closing.
My state used to have 6 pm closing many years ago. It contributed to hyper-binge drinking. So much so that the closing time behaviour was described as "the Six o'Clock Swill". We even had a special police patrol duty (not me doing it I wasn't in the job then) where three coppers in a waggon would go around the pubs in the cbd (and there were very many pubs) chucking drunks into the waggon. Not very good.
Anyway we relaxed our licensing hours and the world as we know it hasn't come to an end. It's actually more civilised. You can get a drink in a restaurant or cafe without having to order a meal or you can just toddle off to your pub with its extended hours.
On my next visit to Britain I shall look forward to a leisurely couple of best bitters at lunchtime without the fear of being flung out on the footpath for the offence of being sober and wanting to do something about it
