Winning The Grocer 33 store of the week is no fluke. It requires spotless standards and flawless retail basics from a well drilled, passionate team, topped off almost always by near faultless availability.That’s not easy in the best of times, but for Alastair Havers and his 250-strong team at Sainsbury’s London Road in Southend, they’ve delivered the winning combination during what has been one of the store’s most challenging periods to date: a complete top-to-bottom refit.
