Bartenders too generous?

cocktail
A recent study has shown that bartenders may be serving their customers portions of alcohol that are larger than they should be. Wine and mixed drinks were reported to be about 50% too big, and draft beers about 25% too big. For those who are trying to watch what they eat and drink, the oversized portions can make it difficult to monitor their calorie intake.

Fear not, health-conscious New Yorkers. The study was performed in Northern California, not in New York City, where getting too much for your money rarely seems to be a problem.
