We just saw a lawsuit over the selling of the same amount of beer as a small and a large at Steelhead games. This all-too-familiar scene shows that it is not just beer that is misrepresented in terms of quantity at sporting events.
I have long favored the German approach to packaging that seeks to force the internalization of costs from packaging on manufacturers to give them an incentive to minimize the use of resources. The costs of such packaging is passed on to consumers and society in the form of garbage collections and waste dumps. It seems to be getting worse. We constantly buy food in large bags or packages only to find that they are only quarter or half full.
