Some cafe owners in the U.S. are now fighting back against customers taking advantage of the free WiFi connection in their restaurants. Though the service attracts more customers, it also caused problems, i.e., some would buy nothing or if ever they purchase anything, it would be cheapest item. There are also instances when people would stay longer than usual, leaving no available table during the lunch rush. Among the strategies employed my owners include politely asking customers who bought nothing to purchase an item from the menu or turning off the connection. Others have started asking for fees as a way to restrict access particularly during peak hours.
