By applying the «Server POSITIVE» software to interact with the "Family Ticket" program, each of the participants (for example, entertainment centers) will receive additional customers. Working with this program, each of the partners, when selling several tickets in one hand (for example, family), gives the right to receive a free ticket or a discount on the purchase of a ticket from the partner entertainment center. Having received the right to such a valuable gift, the family or company will want to realize it and will visit a partner entertainment center. This creates conditions for visiting the entertainment center by customers who have not previously planned to do this.
