I was in Waitrose today. It's not particularly unusual for me to be in Waitrose, I admit. I love Waitrose, it's like the other supermarkets; but it's full of lovely things rather than just tins of beans and sad looking vegetables. Anyway, less of my middle-class prejudice. I was in Waitrose Canary Wharf earlier buying some cartridges for my fountain pen and also needed some groceries from downstairs. It turns out that they have changed their till system so it's no longer possible to pay for items from "upstairs" in the grocery bit downstairs. It used to be one of the pleasures of shopping there that you could pick up a towel or a pair of pants from upstairs and then pay alongside your grocery downstairs - but since they put the new tills in downstairs, it didn't work anymore. I had to queue twice. Oh, the horror. I didn't wander much around Canary Wharf, but I did pop into Gap. I've reached that age where I feel "a bit trendy"
