Abstract: A system for serving customers in a specific queue sequence at a plurality of service points in a bank or post office, for example, makes it possible for customers to select a specific service point, at which service is desired, while maintaining a turn-number system which is common to all the service points. If a customer indicates, when being allocated a turn-number, that he selects a desired service point the system registers the indication in a memory unit. The customers are served in numerical sequence at the service points which are free, and any selective customers are served at their desired service point, preferably when the correct number comes up, and as the selected service point becomes free.
