Canadian culture has many foibles, and one distinct flaw in made-in-Canada social interaction is the need for alcohol to be part of the most male-female courtship interactions. Perhaps this comes from our anglo-saxon heritage, because I don't see alcohol-as-precursor-to-sex in many other global cultures.  "Pick ups" here don't happen in cafes, they happen exclusively in bars and at parties.  If there is no booze present, Canadians are more often introverted or reflective.  With a beer in hand, both genders ease into that sex-is-possible banter not allowed any other time. Coors and Molson beers ads notwithstanding, this cultural bottleneck should be fixed . . . .  women's safety would be enhanced as a result.
