推断题。Roberto担心新雇的员工没有一些外烩经验,造成麻烦。根据原文,“but I am worried about having  inexperienced people working directly with our guests.I am talking  about catering staff here.If we want to offergreat service,we need experienced,trained, competent waiting staff,not people who are going to cause trouble in my kitchen all the time.”可推断出答案为c。
