My brain is in superactive mode this morning and wants to Write All The Things. However, the first thing I must do is to report that I had further communication from Lisa Sutcliffe of Asda on Friday. She was sorry that I was unhappy with her response but said that she couldn't provide details of internal investigations. However, she assures me that they are taking action, which is good to hear.
I've also realised that if I were A Good Blogger, I would have tagged all my posts so that everything is nicely linked for readers who are interested in a particular topic. I will try to a) work out how to do it; b) do some retroactive tagging on (at least) recent posts.
