# System Behaviour

## Web/App

The system will automatically verify the address against the defined delivery zones. If the address is outside all defined delivery zones, the venue will be **greyed out** and the customer will be unable to place a delivery order.

## POS

For Delivery orders in the POS, staff may **override** delivery restrictions at their discretion when taking an order manually in-store or over the phone.

If the address entered is **outside the serviceable delivery zone**, a message will appear alerting you. You'll be prompted to either:

* **Accept the order**, with the option to add or waive a delivery surcharge, or
* **Reject the order**, if the venue chooses not to serve that address

{% hint style="warning" %}
The ability to edit delivery surcharge is controlled by three different permissions:

* User can edit delivery surcharge — for clearing or editing the Delivery surcharge field.
* User can waive delivery surcharge — for waiving delivery surcharge
* User can waive all delivery charges — for waiving all delivery charges (basic + surcharge)
