In Canada, we do not worry about things like the amount of beer you get in a glass. You may as well - and often do - ask for a "big" or "small" glass of beer as opposed to a pint. And what is "big" or "small" in one place bears no resemblance to what is on offer down the road. "Pint" can mean anything from the 12 oz standard bottle to the UK pub pint glass at least 20 oz. A "half" needn't necessarily be 50%. In the Halifax of my youth, you actually ordered "two" which meant two eight ounce glasses. In the Upper Ottawa Valley "pinting" is just a euphemism for the act of drinking. But in British Columbia things are even worse as regulations actually require that confusion be the law of the land:
The federal government insists that anyone who claims to be selling a pint in Canada had better pour a full Imperial pint measuring 20 ounces, or 568.26 millilitres. The province's Liquor Control and Licensing Branch, however, stipulates that individual servings of draft beer cannot exceed 500 millilitres or 17.5 ounces. In a random survey of 15 pubs in Metro Vancouver that advertised ``pint'' sales, the Vancouver Sun found pubs served 17 ounces on average, representing a three-ounce discrepancy with the federal law, but within the bounds of provincial regulations.
Excellent. I am used to the idea of Federal and Provincial law implicitly conflicting with each other but you would think that one regulator might check with the other. To be fair, in many places, the actual serving size - whatever it is - is set out by ounces or millilitres in the menu or on the chalk board. Unlike the US shaker glass question - which I discovered is not about minor Protestant furniture making sects at all - this is also not really about some maybe trying to rip someone off. There is just no concept of a standard bar serving or even the consumer demand for it. Unlike in Britain, no one really cares how much is in one unit of beer. Maybe it's because we Canucks just measure consumption by the number of units, by how many beer we had last night - not exactly how much.
