The Honor Oak Supermarket?? I've found the staff there friendly. Occasionally slightly too friendly like the time the chap told me in detail about the terrible cold he'd had, but you can't fault him for an amiable willingness to chat.

Still, as long as we're shopping locally each to his own.

and yes, I forgot Jumping Bean which is a life-saver when on the way round to a birthday do, and the chip shop which was nice.
