陀螺

Today's hotel general managers are like a whip top spinning around to handle various administrative duties , and there seems no end of meetings, e-mails, financial reports and other paper or electronic documents, which engross such attention that they seldom have time to meet with their guests in person .

如今酒店的总经理总是像一个陀螺那样不挺旋转，辗转于各项事物之间，开不完的会议、看不完的资料和邮件、做不完的财政报告，甚至没有时间来到客人中间走一走。
