Belinda Rees and Debbie gave the Waitrose experience to members at the June meeting.
They explained how staff are shareholders in the company and have a partnership responsibility for running the business.
Waitrose gives to at least three local charities every month, and distributes many food parcels through His Church in Market Rasen.
The was also the opportunity to sample some produce, including Red Fox Leicester cheese, Sweet Sapphire grapes from Brazil, Lincolnshire plum bread and Waitrose wine.
The evening proved to be a happy and informative supermarket experience.
