The disparity between the size of glasses and the size of standard drinks

Reading about a game on the LCBO website that tests how well you can pour a standard drink, I was reminded of the first set of wineglasses I ever purchased.

I had one or two wineglasses among my worldly possessions already, but I wanted to get some that matched. They were cheap, from the dollar store or something, but they were decently nice-looking and I quite liked them. We christened them with a lovely glass of wine that gave us quite a happy buzz indeed. The next day, I got home from work and poured myself a glass of wine, and...discovered that there wasn't even one glass left in the bottle? How could that be? The two of us had one glass each the previous day, there are five glasses in a bottle, where did the rest of the wine go?

Turned out they were oversized glasses. When you filled them to a reasonable-looking place, they contained two standard drinks of wine (unlike my previous glasses, which, when filled to a reasonable-looking place, contained one standard drink of wine.) No wonder we got such a good buzz on the previous night! There hadn't been any serious consequences to that little adventure, but what if those glasses had been used to serve to someone who had been driving?

This gets me thinking that it would be useful if glasses intended for alcoholic beverages were only available in single standard-drink sizes. Of course, oenophiles would probably complain because they like those oversized bowls so you can get the nose of the wine. So what if there was a line on the glass itself indicating how far to fill it for one standard drink? What if the box they come in or the bottom of the glass was marked with a warning label saying how many standard drinks it holds?

This would probably still garner complaints about the government meddling in commerce and whatnot, so here's a faster and easier solution that should offend no one: the LCBO should give away free glasses. They should be simple but attractive, of decent quality, and sized to make it impossible to accidentally overserve. They should be available in any quantity up to whatever constitutes a normal set of glasses like you might find in a wedding registry. You can just walk in and pick them up, no drama, and perhaps they could even include them with purchases as a value-added bonus at the beginning. Drinking glasses are cheap (I've bought them commercially in a set for as little as 50 cents a glass), the LCBO's profits are high, and hindering accidental overserving surely falls within their social responsibility mandate. The fact that they're given away for free at the place where you go to buy alcohol anyway means that people would have to make more effort to get oversized glasses than to get standard-sized glasses, so more responsible drinking is easier than less responsible drinking.

Personally, I'd still prefer if all alcohol glasses commercially available had to be sized to a standard drink, but I think a lot of people would complain. Giving them away at the LCBO would get the job done for people who don't care what kind of glasses they use and people who do want their glasses sized to a standard drink, without giving those who want non-standard glasses any reason to complain.
