Titles, Rank....honestly its not a big deal is it? QRs allow it if one feels so inclined.
Now masquerading as an Officer thats odd......
I recently had dinner with some friends in the good ol'USA. One member of the group (unknown to me prior) was wearing a USN Officers uniform (LTJG, a couple of meaningless ribbons and submariners dolphins)
After a few questions/answers he told me he left the USN 8years ago having done 2/5s of a dog watch in the USN.
He wasnt in the Reserve/Guard.....he just liked wearing his uniform & hat out on the town from time to time.
A quick show of hands from the other guests revealed that they all thought it was wonderful, patriotic and entirely appropriate.
Poor old LFittNI......you'd have kittens old boy!!!
