Pr00ne,
Indeed uniform in pubs brings the Forces into 'disrepute' apparently. Never really stopped anyone after a freedom of city, Trafalgar 200, Golden Jubilee parade type bash. RN lads take great pride in their 'Square Rig' and find it actually attracts a lot of female attention when worn out on the town on authorised Rig Runs. Can't comment on Army and RAF however. Oxford and London are clearly more civilised than such places as Yeovil, Huntingdon and Stamford. Personally, whilst walking to a parade in uniform post 2003 I have been called a 'fascist murderer' and spat at, which may have biased me slightly.
Certain hospitals do indeed have substantial numbers of military medical personnel and I hope the story of the TA lad was a one off.
