In the '90s/'00s I worked at the Davis Food Co-Op in Davis, CA which was one of the largest full-service (meaning not just hippie health food) consumer-owned grocery co-ops at the time. After working in the bakery I was on the Board for 3 years, a fascinating experience (we followed the Carver Policy Governance model, where the board is basically the legislative/judicial branch and the CEO is executive).

When a Whole Foods opened across town, they shut down in less than a year largely because of the strength/quality/loyalty of the Davis Food Co-Op.
