"Er, no," Rincewind's face falls. He thought he'd been doing better. "Just trying to um," he scrabbles frantically in his memory for the words. "Trying to en-hance the am-bi-ence of the dining ex-per-ience." Rincewind beams, pleased as punch he's remembered. "Here's your veg and potatoes," he sets a steaming dish in front of Lucius. He swallows nervously and turns to Severus. "Your brothy rice." A wide blue plate. "Egg and fruit." A smaller green one. "And spinach in sesame oil. Heated." A final plate, this one square and orange. "Would sirs care for pepper?" An absurdly large pepper grinder remains on the tray. To Rincewind, it looks vaguely like a model of the Tower of Art.
