You both seem to be missing the point, this is not an isolated occurance. When you add up the amount of booze that is taken by the crew at the end of each sector over the whole operation, the cost is pretty substantial.
If, as you both seem to think, that it is acceptable for crew to help themselves to the booze, then is it also acceptable for Despatchers, Engineers, Loaders, Cleaners etc etc to also help themselves?
Theft is theft whatever 'spin' you put on it and as our US cousins say - 'If you can't do the time, don't do the crime.'
