Re the Finns and drinking.
Many Finns I know, of both sexes, will think nothing of drinking a bottle of scotch in one go and the pre departure cognac, even at "crack of sparrowfart", is almost a tradition.
Finns, when they have too much to drink, usually fall on the floor and sleep - a common sight in bars.
They are then collected by the police, for their own safety, and taken to sober up - few are charged with offences as they are generally not aggressive.
In winter falling over, on the way home, can be a problem and the bodies of missing persons are regularly found when the snow melts.
I may be wrong but, although they do drink a lot, I doubt many Finns cause problems by drinking on aircraft.
