>>I find myself of two minds on this one. I agree that this is not something for government control. OTOH, when you and I were growing up, places that sold cups of soda generally had three sizes that were 8, 12 and 16 ounces, respectively. Now, in many places, you can get a 16-oz. soda; the "small" (if they offer small) is 20 oz. or more. It's absurd.

In fact, soda is one of the biggest moneymakers for restaurants. The soda costs them pennies; I think the cup costs them more than the soda.

Water is actually not a good comparison for the US since it's generally free in restaurants. Only high-end places offer bottled water for sale. In most, tap water is provided free and automatically (except in places where there's drought, in which case you have to ask for it).
