# 10.4 Tips & troubleshooting

- **Different timezones:** if stores are in different timezones, set the correct **business timezone**
  (chapter 12) — it's the reference for "today/now" and reminders.
- **A staff member not showing in a store:** check they have an assignment (`StaffMemberStore`) for that
  store and the **service scope** isn't *None*.
- **Can't delete a store:** you can't delete the **last** store of the business.

> 💡 **Scenario:** the manager (Business admin) runs the 3 stores and switches in the picker; each
> barber (Employee) only sees their store and their bookings. Assign barbers who work in two stores to
> both, with **per-store hours** (2.8).
