The Waitrose store on Penn Road in Beaconsfield, Buckinghamshire, won our Top Store award this time last year.

Our mystery shopper reported that the store had phenomenally high levels of customer service.

At the time, store manager Paul Miller said that team building exercises had forged the team spirit necessary to achieve its service levels. When we spoke with Miller this week, he said that the store had been extended, increasing its sales area by almost 9,000 sq ft, to 27,000 sq ft.

Miller noted that the store extension, which was completed in November last year, had been well received by customers, who liked the new fittings and wider product range it allowed for.
