This is a lose-lose situation for Tesco. Refusing to co-operate with Jimmy (and you could tell they were really on the edge of that) is bad publicity but they really don't want what he has on offer - hence the product placement.
The former CEO Terry Leahy has published a management book a year after his departure (during which the share price has dumped 25%). In his book he devotes 4 pages to himself and 20 pages to the Tesco Clubcard. One of my children went to school with one of his: there's more than 4 pages to be written, believe me!
Alongside Tesco's machine-like devotion to systems, data and screwing suppliers its market domination was ably assisted by a succession of own-goals scored by Sainsbury, Morrison and the other chains. Now, and for the first time in my lifetime the Co-op is revitalised while Sainsbury and Morrison have got canny. Recession is the perfect market for Aldi and Lidl so on a level playing field the public's dislike of Tesco is now starting to matter. Waitrose has neatly moved itself further up-market and out of sight of the rest.
