Convenience store aficionados of the world, relax. Your perfect egg sandwich is safe, for now.

The primary concern for millions of Japanese around the ?6.77 trillion ($45.8 billion) bid for Seven & I Holdings was that Canada¡¯s Alimentation Couche-Tard would, in search of improving shareholder value, destroy the customer experience that has made the Japanese convenience store, or conbini, a global sensation. That threat seems to have faded after Couche-Tard on Thursday abandoned its bid, citing a lack of ¡°sincere or constructive engagement.¡±

The Canadian firm¡¯s ill-tempered and unusually in-depth letter should be read in full. It drips with the same sense of entitlement that colored Couche-Tard¡¯s bid for the worldwide 7-Eleven franchise from the start ¡ª as if it expected buying the Japanese rival to be as simple as grabbing something from a store shelf.
