电梯小姐 Elevator operator
（重定向自Lift operator）
电梯小姐（英语：Elevator girl）指搭乘并操作电梯的女性职业，通常出现在百货公司、饭店、医院等地方。在电梯刚被发明时，由于人们不会操作，因此电梯在运行过程中，一般都会配备一位电梯操作员（英语：Elevator operator）。
以前的电梯是需要人操作的。在日本，据说最早设置电梯的是1929年时的松坂屋上野店。当时的称呼是「升降机小姐」（升降机ガール）。电梯小姐穿着专用的制服，优雅地为客人介绍，是女性向往的职业之一。特色之一是做介绍时以独特的说话方式，缓慢而高音，其实是为了不和其他乘客的说话声混在一起。

An elevator operator (in British English, usually lift man, lift woman, or lift girl) is a person specifically employed to operate a manually operated elevator. Manual elevators were often controlled by a large lever which would cause the elevator to stop or run and sometimes also regulate speed, and typically required some skill or sense of timing to be able to consistently stop the elevator level with the doorway of a floor. Besides their training in operation and safety, later, department stores extended the roles of operators as combination greeters and tour guides, announcing product departments, floor-by-floor, and occasionally mentioning special price offers.
