Lazy Susan.

A friendly waitress Susan works a double at an everyday Cape Town restaurant, deftly serving gluttons and wasps, hipsters and high-tippers, racists and lechers. With some effort she maintains both wit and service in the face of obnoxious customers--until a lousy tip gets the better of her. Told from the perspective of a single lazy susan (rotating tray), this is dark comedy and social commentary at its best.
