I must apologise. I did assume that was what happened but with a 1pm deadline for the story, I had to use "journalistic licence" to put my spin on it and get my copy in.
Of course if Tesco complain, I will take "full responsibility" for the "mistake". The Editor though, has assured me of his "full support". In other words, if Tesco threaten to sue, I will be the "fall guy" and the boss will "kick me down the stairs". In my defence, I will tell Tesco that they are getting lots of free publicity. That should satisfy them.
