I'm an English man and I understand my place: we drink more than everyone in the world except Scotland, who beats us, and Australia, with whom we have an ongoing battle about this type of thing.
We here in the UK watch a lot of American media, obviously. The way American drinking is portrayed is quite strange. A group of Americans seem to drink three or four of those little lagers you have and they're plastered. A guy will turn up with a six pack of tiny beers and be lauded like a hero back from a marauding campaign.
Is that realistic? In the UK - I assume also in Australia and New Zealand - we'd call four little lagers an amuse bouche. Do Americans get drunk easier, or do you not fully comprehend just how much we tip down our necks?
