Not really relevant to this thread but I was once in Morrison's and a lady filled her trolley with the cheapest loaves of bread and the cheapest tins of beans, you know the type, tin of juice and three beans. I thought to myself, " I bet she runs a B&B." Some weeks later the same thing happened with a Chinese lady who cleared the shelves of the cheapest rice and sliced carrots. "Runs a takeaway", thought I. Sure enough, a while later I ventured into a rather seedy-looking, run-down Chinese takeaway in town which I had never patronised before and lo and behold, there she was. I didn't order.
