Sir; re your articles on the evolution of the supermarket, The Grocer, November 3. Your omission of Caters Supermarkets, which provided leadership in fresh food supermarketing at that time, needs to be corrected. In the early 1960s we had sales that would put many current retailers to shame, with store turnovers of £40,000-£70,000 per week, out of 9,000 sq ft, were the norm, with staffing levels of 200 plus per store. In 1972 it was an immense loss to both company and industry when the chairman Leslie Cater and Francis Wallis (chairman of FJ Wallis Supermarket) were killed together in an aircraft crash over the Pyrenees. I am sure many of our competitors breathed a sigh of relief when Caters were sold to Debenhams in 1973. Barry Woods Earlsfield, London SW18 {{LETTERS }}
