  This paper introduces benefits and detriments of a robot bartender that is
capable of adapting the interaction with human users according to their
preferences in drinks, music, and hobbies. We believe that a personalised
experience during a human-robot interaction increases the human user's
engagement with the robot and that such information will be used by the robot
during the interaction. However, this implies that the users need to share
several personal information with the robot. In this paper, we introduce the
research topic and our approach to evaluate people's perceptions and
consideration of their privacy with a robot. We present a within-subject study
in which participants interacted twice with a robot that firstly had not any
previous info about the users, and, then, having a knowledge of their
preferences. We observed that less than 60\% of the participants were not
concerned about sharing personal information with the robot.
