I read this short story somewhere between 2002 - 2010, but I remember the book I read it from was very old and tattered, so I think it was likely quite old when I read it.
The child asks the robot to give it milk and play chess at the same time, but the robot is designed for single tasks only. Then the child cries and tells her mom that the robot hit her. When the mom calls to complain, the support person tells her about the three laws of robotics, and why it's impossible that the robot hit her. The support guy offers some other robot and the story ends there.
