IIRC, 'batting' entitlement disappeared in 1970 with the advent of the 'Military Salary Scheme'. Thereafter, although there were still some Officers' Mess 'servants' (the official term, not mine), the level of 'service' provided was extremely variable. (Yes I know about navigator students and the 'teasmaid' at Finningley). But we were still entitled to wake-up calls and a cup of tea first thing until the bean counters stopped that, promising that rooms would be provided with tea making facilities instead. Which didn't last long.....
SAC 'flight kitchen' in-flights were...OK. I hated 'buffalo wings' wrapped in miles of cling film though and never did develop a liking for 'sour cream flavoured ripple chips', but the 'po boy' sandwich (if it can be so described) option was incredible. A large baguette filled with various cold meats, tomato, lettuce, pickles, spiced mayo etc. which was virtually impossible to eat in one hand, but very tasty!!
