>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.

It just reflects that service cost has grown more than ingredient cost. Or that it is cheaper for both vendor and consumer
that perhaps part is left not consumed, but price/value equation is still optimized.
Reflect on the prices of water in restaurants, even deducting the higher priced beautiful bottled one cost
to "compensate" in customer perception for the high price asked for the service.
I would gladly pay double for triple or more volume - that is in addition to one or two bottles of nice wine if in a group.
