The question is: How do want it to work for you?
First, start with searching the forum for Person Count or Guest Count.
You could have a fixed rate “product” that is added to the Ticket in the Quantity of the Guest Count.
Or, you could use a Ticket Calculation that is added to the Ticket as a charge based on the Guest Count.
Or, maybe something else… SambaPOS is very flexible so that you can suit its operation to your needs or requirements.
