Scientists from the Norwegian Institute of Alcohol and Drug Research sent nine drama students to feign extreme drunkenness in 153 bars in Trondheim, Bergen and Oslo.
What they discovered may bring a new perspective to many a lost night.
The bartenders served the pseudo-trollied young actors a brain-battering 82 percent of the time. And if they were a woman, and the bar was a dark, loud, late-night venue, that rate rose to an astonishing 95 percent.
This is despite the fact that it is in theory illegal under Norwegian law for bars to serve anyone alcohol who already appears to be intoxicated.
“Over-serving was more likely at late hours, in venues where most patrons were clearly intoxicated, in venues where the music level was high, and when the pseudo-intoxicated patron was female,” Kristin Buvik and Ingeborg Rossow, the two researchers, concluded in the report, which is to be published in the journal Addiction.
