Not all beverages. Beer is typically sold in 12-ounce bottles or cans. Possibly a U.S. pint (0.47 litre) at a bar. Soda is often sold in 12-ounce cans. Of course a pour of hard liquor at a bar might be anything; the 1.5-ounce shot isn't mandated by law.
I bet you were thinking of hard liquor at 750 ml (down from the traditional fifth at 757 ml), or 2-liter bottles of soda.
