This study examined the effects on tips left by black and white restaurant patrons of having a white waitress sit down or lean over at the table during the service encounter. A significant server posture by patron race interaction was obtained. Sitting at the table significantly increased the tips left by white patrons and marginally significantly decreased the tips left by black patrons. Potential explanations for this interaction are discussed along with its practical implications.
