In Korea, a waitress is commonly referred to as "웨이트리스" (weiteuriseu), which is a loanword from English. In more traditional settings, the term "종업원" (jong-eobwon) can also be used, meaning "staff" or "employee." In casual contexts, people might simply use "언니" (eonni) or "아줌마" (ajumma) to refer to a waitress, depending on the age and familiarity.
