Vets visiting a UK Officer's Mess
I've just had a surprising conversation with a suspected walt who asserts categorically that any UK ex-officer has the right to invite themselves into a UK Officer's Mess/Wardroom as a guest and to dine there as a visitor at own expense.
I expressed surprise (well, disbelief actually) citing security questions in the very first instance but was roundly admonished.
I think I can guess who is correct but can anyone confirm please?
