The Guest Control function will show or hide the ability to select guest numbers for an order. If you want to map items on a check to seats at a table, you would want to use this feature.
If the Guest Control is enabled, you can add the number of guests, at the middle-bottom portion of the POS screen.
The order can be placed for each corresponding guest, by selecting the guest number. Once items are added for each guest, the corresponding order will display the guest number.
