at your service 听候吩咐;乐意效劳；愿为您服务

酒店或餐厅服务员经常会说的一句话，当你在餐厅用餐，或住酒店有事找服务员时，他们通常都会先说这句话。

另外，古代的臣子、仆人接受国王、主人的任务时，理解成愿为您效劳（效力，效忠），剧本里常这样用的。

有时候，也表示对对象的尊敬，表示愿意帮忙。

You can use ‘at your service‘ after your name as a formal way of introducing yourself to someone and saying that you are willing to help them in any way you can. 当你在向别人介绍自己时，可以在名字后面加上这句话，来表示你愿意尽你所能帮助他们，是一种正式用法。例如： She bowed dramatically. ‘Anastasia Krupnik, at your service,’ she said. 她深鞠一躬，说道“阿纳斯塔西娅·克鲁普尼克，乐意为您效劳！”
