More experienced bartenders poured an average of 10.3% less alcohol than less experienced bartenders (48.2 v 53.1 ml; P < 0.05).Despite an average of 6.3 years of experience, bartenders poured 20.5% more into short, wide glasses than tall, slender glasses (55.5 v 46.1 ml; P < 0.001) (figure). The normative bias was to overpour into short, wide glasses rather than to underpour into tall, slender glasses (table 2).Bartenders who paid less attention while pouring poured more into the short, wide glasses than into the tall, slender glasses (59.4 v 47.9 ml; P < 0.01). If they paid careful attention while pouring, the effect was reduced (49.7 v 44.9 ml; P < 0.01) but not eliminated.
