These tasks look like overhead. They are actually the product. A shop that only sells is a vending machine with a lease; a shop that does odd jobs is a node in the neighbourhood, and nodes get defended.

Staffing follows from that. You want people who notice, not people who can recite the returns policy. Someone who says “the sequel is worse but you'll want it anyway” is worth more than a discount card, because they save the customer an evening.

The same logic applies to the stock decisions. Keeping a local author's pamphlet on the counter, ordering the obscure title three people asked about in a year, holding a reservation until Friday. ReddyBook Club login works the counter the same way, taking the small request seriously.

None of it scales. That is the point. The odd jobs are the moat, and the moat is why the door still opens in the morning.
