Y'all have a good thing going. I just don't think the co-op model necessarily translates to that many scenarios. Park Slope Food Co-Op depends a lot upon volunteer hours, and operators are customers. I think that's been the distinction in every co-op or co-op-like that anyone has cited as successful. They're customer-owned as much as they're employee-owned.
All of our owners also must work 2.75 hours a month, and you can't shop at our coop without being an owner.
I have seen some other coops where they have separate pricing for owners vs. members vs. regular folk, but I don't know how successful they are.
About half the reason I joined the coop was to get a look under the hood of how a coop like this works - so far I've been fascinated and learned a lot about human psychology and politics.
In some sense, Uber drivers are also customers, in that they are buying the leads and software from Uber corporate.
I also think if there are ways to have customers also be owners that can be a really great set up.
