You'd be surprised where subs have got to in the last thirty years, both ours and thus possibly theirs.
I know exactly how close theirs got back in the 80s but if I told you I'd have to kill you! I well remember one panic when it got so busy that we finished up with the whole of 42 detached to ISK to give assistance. The scruff bar has never made so much money. At the end of det party Henry the Hoover burst his bag after 11 pints of heavy!
