A server call system that enables the customer to be in direct contact with the server at all times. A keypad is disposed at customer locations and adapted to receive item requests from the customer. The keypad is in wireless communication with a server pager carried by a designated server. The customer inputs an item request into the keypad and it is sent to a predetermined or dynamically determined server pager for fulfillment. In this manner, not only is the efficiency of the establishment increased by eliminating wait time by customers for submitting a request to their server, but the server can effectively serve more areas with less direct customer contact.
