After imbibing in several messes there seems to be a vast amount of differing traditions on this, obviously all involve passing to the left and pouring for a lady however: 1. Decanter not to leave table 2. Decanter not to touch table 3. Decanter lifted over your glass 4. Pour your own 5. Pour for the person on your left Sure there are many more out there. Is there a "correct" way or does it come down to Corps/Regt/Unit traditions or does it not matter as long as the Port keeps flowing?
