Managing Hire Products
For hire products you can theoretically manage bookings for each item on "Bookings" tab for the product, although such level of management is hardly needed.
When administrator is managing bookings they are not constraint by office hours or staff working hours. They can even create overlapping bookings if it makes sense
Administrators can create repetitive bookings (choosing booking frequency on booking creation form). In this case they have to set both booking start and finish date. Repetitive booking can be useful for example to exclude staff lunch time from availability.
