Why this one

The jaffle shop from the dbt tutorial is a fixture: a few CSVs with a fixed date range and an ending. It serves the tutorial and stops.

This one keeps trading. A few regulars account for most of the revenue while the long tail visits once. The seasonality is strong enough to survive a group-by. Because every run with the same seed produces identical bytes, the models you build against it today reconcile against it tomorrow. And because the shop keeps business hours, even the quiet stretches make sense: nobody buys a jaffle at four in the morning.
