Delighted Nick, now that I know that your little tale was basically a crock and should not have been taken seriously, which begs the question why you felt compelled to mention it - it has nothing whatsoever to do with the thread.
By the way as to who thought they were being intimidated:
1. Who ended up "effing" and "blinding"? - You by your own telling of the story.
2. In describing the end of the exchange it was you yourself who wrote this - "Landlord looks like a mongoose viewing a snake but decides he had better back down on the grounds that he is about 5ft 6' and I am 6ft 2' and from South London." - It is perfectly clear who you thought was doing the intimidating.
