The list that Mrs S dictates to me (and which I take down in my best handwriting...) are always clear and precise, but it's the additional level of detail that makes shopping for her such an enjoyable experience (and occasional challenge)...today it was essential that the broccoli was English, the Beef Burgers Scottish, the Cheese Spanish, and that I try to find the "greenest of the bananas" (for which she did compliment me on my selection upon my return). I thought I knew my way the world's politest supermarket, but shopping for Mrs S takes it a whole new level!
