South Carolina, in an unexpected bit of rationality, repealed their mini-bottle law a few years ago. The law originally came about because the Southern Baptists in the state felt that limiting hard liquor to being sold in small 1.7 oz (50 ml) bottles was the way to prevent the sin of drunkenness. A peculiarity in the law meant that the bottle had to be opened in front of you, and the entire contents used to make your drink (to prevent bootlegging and watered-down drinks). So if you wanted a drink that had 2 or 3 ingredients, you were getting a pretty stiff drink.

Someone eventually pointed out that they were the last state in the Union serving drinks this way (other than the airlines) and all those tiny glass bottles ended up in the landfill. So in 2010 the state went free-pour.
