Silent salesmen

The vending machines, when installed, sell the products itself. These machines are fully automatic and don’t require any particular person for the salesmanship. Vending machines do all the work, 24 hours a day, and 365 days a year, itself. These machines always work and never take rest. These machines deliver items anytime. They work hard and never go on vocations. They display the products to every passing person, collect cash in advance and then deliver the product to the clients. Your job is to keep your machines serviced and stocked with desired products. For good sale of merchandises, and to attract clients, the vending machines must dispense most favored products. Also they must be placed at most visible and appropriate location.
