顧客怎麼翻譯英語

① 請教各位英語達人，「客戶」，一般有倆個翻譯，customer,client，這倆個單詞的用法有什麼區別啊

朗文上給的解釋：
Customer is the most general word. A customer is someone who buys something from a particular shop. People who pay to use something such as a transport service can also be called customers : A customer came in and bought several jackets. |Customers are advised that the next train is delayed.
A client is someone who pays for a service : a hairdresser and her clients
就是說Customer指比較普通的商店顧客之類。而client多是指商業版上的客權戶。

② custom和customer翻譯成顧客時有什麼區別

custom
n.習慣，慣例； 海關，關稅； 經常光顧； [總稱]（經常性的）顧客
adj.（衣服等）定做的，定製的
customer
