Ok, I looked it up. Still pushing it with 3 schooners there Musky
What beer was it?
From the info I looked at, I like the way SA refers to a British pint as an 'Imperial' pint but the SA 'pint' is actually a 450ml schooner.
If I was in Aus, I'd go for the jug and drink it quick before it got warm (might be more cost-effective too?)

Sorry Worty, I'm gonna have to correct you there in SA its even worse that:
Imperial Pint (UK Pint) 568 ml (a proper man's drink)
South Aussie Pint 425 ml or 15oz (in other words a generous half)
South Aussie Schooner 285 ml or 10oz (for someone who doesn't really want a drink)
Butcher 200 ml (honestly why even bother!)
Pony 140 ml or 5oz (on a hot day get in quick before it evaporates!)
Jeez

Cheers BoN - it'd go like this for me:
Jug - warm up for a sesh.
Imp Pint - what follows a jug in the sesh.
SA Pint - that ain't a pint like a kilometre ain't a mile - just get a pint.
SA Schooner - just get a pint.
Butcher/Pony - cheaper to get a pint rather than two butchers and a pony.
TBH - a butcher would be what I'd have whilst my pint/jug was settling. Most of the time, a half pint here is merely a taster to see if it'll do for a sesh, or an emergency drink to wash the dust out of yer throat.
Most cans (tinnies) of beer here are 440ml with the occasional 500ml. Bottles are usually 500ml, but rarely get the 568ml (pint). There are some bottles/cans that go to 330ml or even 285ml very occasionally - but I really don't see the point in them.
Do people really drink butchers and ponies - why? I was going to include schooners but, being a half pint over here, I can see it if you want to try a few beers at a decent pub.
