OK, thought I'd throw this one into the pot and see what happens. Chatting to a friend last week, a RN Officer (sorry but some of them have mates). For the past 4 years he has succesfully claimed ALL of his mess bills and mess associated fees back from HM Govt based on the fact that he has no choice in attendance. This has included costs for "3 line whip" dinners, summer ball etc. This has amounted to approx Â£1500 per year! Am I missing a trick here? along with most of the Armed Forces? OR has he been very lucky to get away with it so far? Thoughts please as i have a lot of adding up to do and I want to know if it's worth it.
