A recent episode proves the adage that you can't please all of the people all of the time.

One Ocado customer - we'll call her Mrs M - specified with her order that her driver should be a "strong man" because she lived at the top of 88 steps.

Did she get her wish? No - as this memo from an Ocado customer services operator to his manager shows: "Mrs M was unhappy that her driver was a small lady. " Who says size isn't everything?
