Reminds me of the time on an Iranair flight from LHR - JFK,
Faced with crossing the Atlantic without booze for the first time as this was a dry flight I resorted to the old trick of emptying out a litre water bottle and fill to brim with vodka.
The flight was fairly empty ( funnily enough it was during the time when Iraq invaded Iran ) but one of the stewards got suspicious when I called for my fifth OJ.
However,when I poured him a large screwdriver he sat down and we had a great old time crossing the pond.
Happy days.
