To give the customer an added value to the duration of their wait as well as lowering the perceived time of waiting, a variety of different queuing systems can be used. It can vary from a small simple system for a single cashier and customer group up to a very advanced system with hundreds of cashiers on different floors, different locations and for different customer groups.
The basic idea is the same for all queue systems. Each customer takes a ticket number which represents their turn in the queue line. The customer then doesn ?t have to stand in line and take up valuable store space; instead it allows the customer to for example sit and read a brochure, a book or to watch a customer-TV until their number is shown on the display or on the customer-TV.
