A pint no less.

A bill in the Oregon House calls for honesty at the bar. It would allow the Liquor Control Commission to issue decals to establishments that meet the "honest pint" standard--by monitoring how much beer a serving contains. "If someone advertises a pint, don't you think you should get a pint?" says Representative Mike Schaufler, a co-sponsor of the bill. Apparently this is a concern around the world. According to The Oregonian, England and Germany measure the amount of beer served with a line on the glass that allows everyone to see just how much liquid, and how much head, one is getting.
