A call-out is a situation in which a worker is asked to leave their base and come to someone’s house, shop, or the roadside to help or repair something — a plumber in the night, a mechanic for a car that will not start, an engineer for a machine at work. You have a call-out; the firm may charge a call-out fee just for arriving, before any fixing begins.

A call-out is a situation所謂call-out，是一種情況：in which a worker is asked to leave their base工作人員被要求離開駐點 and come to someone's house, shop, or the roadside到某人家裡、店裡，或路邊 to help or repair something去幫忙或修理東西——a plumber in the night像半夜的水電工、a mechanic for a car that will not start修發不動的車的技師、an engineer for a machine at work修理工作機器的工程師。You have a call-out你就是叫了一次call-out；the firm may charge a call-out fee公司可能會收call-out費（出勤費），just for arriving光是到場就收，before any fixing begins在還沒開始修之前。

Though actually, this noun is especially British and trade-like. American English more often says a service call, a house call, or “they came out.” And the verb to call someone out is a different, newer use: to challenge them in public. That is not this entry.

Though actually不過事實上，this noun is especially British and trade-like這個名詞特別英式、也帶點行業用語的味道。American English more often says美式英文比較常說 a service call「service call」、a house call「house call」，or "they came out."或者「they came out」（他們有來過）。And the verb to call someone out而動詞to call someone out is a different, newer use是另一個比較新的用法，to challenge them in public意思是公開挑戰某人——That is not this entry那不是這個詞條。
