The other down side to the new system will be its impact upon crew social events while detached. Appreciate its not going to be a consideration for the policy makers, but imagine the reaction of most restaurants when 20 crewmembers pitch up for a social gathering and ask for individual bills/receipts. Ok, it will be the end of whines like "he had the extra poppadum" but I see it killing off one of the more enjoyable aspects of Service life.
