Nightingale supporters gathered at a London West End venue to check out the reasons behind the success of Sainsbury's.
Addressing the inaugural Young Nightingale business lunch, company chairman David Tyler discussed the fundamentals in running a major supermarket chain - customer service, good quality products and competitive prices. Sainsbury's earns £60 million on an average day.
He also touched on the difficulties retailers face in a harsh economic climate.
Outside of his business life, Mr Tyler is actively involved in Nightingale as a trustee of the south London home.
"Nightingale is a charity close to my heart," he said. "My mother has been a volunteer at Nightingale for nearly 40 years and she was the one who introduced me to the charity. I would encourage anyone who hasn't been to the home to go and see the wonderful facilities it has to offer to the community."
The lunch raised more than £16,000 and thanking guests, Nightingale chair Harvey Rosenblatt said: "It is fantastic to see so many young people here today."
