【答案解析】[听力原文]
M: Nicole. We're a little short of staff this evening since three of the waitresses are off today. So I'm asking the trainees to help out. Could you work for Sarah to serve food to the guests in the Diamond room?
W: Sure, no problem. But will there be enough people to help with the seating in the garden?
M: I think Megan can handle it with the rest of the staff and I can help out if necessary. If you need me, let me know. I'll be supervising the stockholders' meeting down in the Grand Hall.
W: Okay. I'll go and change into a uniform.
