Sunny is very impressed by his balancing skills, and she wonders if he has ever worked as a server in a restaurant. They all seem to be very skilled at carrying trays with plates and cups and bowls on top, usually without even spilling anything. She doesn't know if that is a prerequisite to the job, or if it is something most people pick up after training. She didn't need to balance trays of plates and cups and bowls when she has had jobs.
