40ml is a decent double tot. I would not want more than that in a single drink anyway. Especially if its a strong liquor!

40ml is 1.3 oz so not even a double. I didn't realize the Norwegians were all drinking weak cocktails!

For some reason I had in my mind that a shot was 20ml, but clearly I'm wrong.

A cocktail with only a single shot of liquor, especially if the rest of the drink is large volume, is pretty weak I agree.

In Australia, a nip of alcohol (spirits) is 30ml - so anything involving more than one ingredient is generally multiples of that.
