The goal is to customize the PoS interface so that the existing “Order” button (or a new adjacent button) can be overridden or extended to trigger a custom behavior: when the button is clicked, a popup window should open with a text input field. The cashier or waiter can type information such as the name of the person placing the order into this field. After entering the text and clicking “OK”, the popup should close and the order can then be confirmed as usual.
