Hee Hee I found the comments a lot more fun than the article. What a plonker. I was wondering which was you until I came to GUM.
Yes, thanks for the lead to the comments - excellent and beautifully English, mild vitriol.And yes, I think Sarah's secret is out: Grand Union Motor, no?
My first choice was just GrandUnion, but interestingly, it was already taken. I'm hopeless at thinking of things like that on my feet when my head was ful of articulating my mild vitriol.
