日常生活中，如果我們說，某某是我的飯票，那就是說，某某為我提供主要的生活來源。其實(shí)，英語中也有相同的用法。Meal ticket一詞除了字面表示的“餐票”意思之外，也可以指某人的生活來源依靠。

Meal ticket may refer to a) a ticket that entitles the bearer to meals in a specified restaurant, especially when meals purchased in this manner are offered at reduced rates; b) someone upon whom one is dependent for one's income or livelihood, for example, selfish children who look upon their father only as a meal ticket; or c) something, as an object or ability possessed by a person, that is necessary to that person's livelihood, for example, the radio announcer's voice was his meal ticket.

Meal ticket（飯票）可指在指定餐館就餐的餐票，以此種方式就餐通常可以享受折扣；或者指某人收入或生活的主要來源，如，自私的孩子們只是把自己的父親當(dāng)成了飯票；或指某人賴以生存的一個(gè)物品或一項(xiàng)技能，比如，電臺(tái)播音員的聲音就是他的飯票。
