(Maitre'D 2005, from Service Pack 1 and later versions of Maitre'D)
You can skip Table Zero (0) guests from the customer count in the reports
for Bartender, Fast-Food and Order employees. This is useful to avoid
double count of a client who orders a drink in the lounge until a dinning
room table is ready, for example.
P.O.S. Control / Employees / Configuration / Order
No Customer Count:
Enable this option to disable guest counting on Table Zero (0) for ANY
client of these employees.
Note: This option disables, for Table Zero (0), the Count Customer
button of P.O.S. Control / Screens / Screen Layout Setup.
