contents Playful deception, a common feature in human social interactions, remains underexplored in Human-Robot Interaction (HRI). Inspired by the Turkish Ice Cream (TIC) vendor routine, we investigate how bounded, culturally familiar forms of deception influence user trust, enjoyment, and engagement during robotic handovers. We design a robotic manipulator equipped with a custom end-effector and implement five TIC-inspired trick policies that deceptively delay the handover of an ice cream-shaped object. Through a mixed-design user study with 91 participants, we evaluate the effects of playful deception and interaction duration on user experience. Results reveal that TIC-inspired deception significantly enhances enjoyment and engagement, though reduces perceived safety and trust, suggesting a structured trade-off across the multi-dimensional aspects. Our findings demonstrate that playful deception can be a valuable design strategy for interactive robots in entertainment and engagement-focused contexts, while underscoring the importance of deliberate consideration of its complex trade-offs.
