All across the US, draught beer drinkers are routinely "cheated" by the us of thick-walled mugs of small capacity, often paying more for a 12 ounce draft than for a bottle or can of similar capacity, while the establishment's gross profit from the barrel is much higher. Once a barman, back in the halcyon days of my college career, I've always been amazed that more folks don't recognize and fight back. I see nothing wrong with the "state" (and in the US, almost all "liquor laws" arise from individual state legislatures) requiring that beer glasses/mugs/tankards/horns/etc. come with the capacity clearly marked.
After all, every other alcoholic beverage container has the volume clearly printed on the can, box, bottle or label.
