Perhaps Ahold Delhaize were guided by the spirit of the English saying: "One for a wish, Two for a kiss, Three for a letter..."?But, whatever the motivation, on the very first workday after leading Dutch grocer Ahold and number two Belgian retailer Delhaize merged last weekend, they sent a "welcome letter" to their top 100 suppliers in the Benelux expressing a heartfelt desire for "a good future relationship".In the brutal cut and thrust of modern-day business this kind of thing can only bring tears to one's eyes. After all, love between retailers and manufacturers is as beautiful as it is rare. Doubtless, however, all was in a good cause. For how else could this new retail giant give expression to its joy now that it posts around €63bn in annual sales in a total of eleven countries, including Germany and, somewhat improbably, Indonesia?Like children clinging to the hope of Santa Claus on Christmas Eve, trusting food producers and fmcg manufacturers would want to believe that the celebratory letter-writing exercise was motivated by a deep spirit of altruism and brotherly love. But a bad grown-up in the shape of Bernstein has shattered this belief for ever.
