Ask yourself the following: Is your bartender sloppy, cavalier, or imprecise when pouring your favorite micro-brew, or is he just trying to increase his profit margin?

When your local pubs say they are selling you a pint of beer, you should get a pint (i.e., 16 oz). Not 12 oz or even 14 oz, but 16 oz of beer. A "pint" is a standard U.S. liquid measure,  or precisely 16 oz of liquid.

As it turns out, the majority of the volume in a standard US pint glass is in the relatively small height in the top part of the glass. In fact, if a beer is poured to within about 1/2 inch from the top, 13% of the beer is GONE.  If the beer is poured to about one inch from the top of the glass, an astonishing 25% of the beer is missing from your pint. This is shown visually at The Beer Gauge website.
