The "Flag Butler" signal/flag improves the communication between waiters/servers or attendants and the customers. The waiters/servers or attendants will not have to continually ask if each person needs assistance, which takes up time and sometimes becomes a nuisance to the customers. The waiters/servers or attendants can spend more time getting orders done efficiently. The signal/flag is easily visible in contrasting colors to its environment.
