Tom: we are going out for dinner tonight. Are you coming, Betty?
Betty: I'm not sure. I have to check my schedule. Where are you going?
T: oh, Jake made a reservation at Friday's.
B: Jack?
T: yes, the one with the R$D team. Is that a problem?
B: I will never go out with him anymore.
T: why did you say so?
B: last time when we had dinner at the Smith's, it was a horrible experience. He had no manners at all!
T: oh, really?
B: he made a lot of noises while eating. He talked with his mouth full and sipped loudly.
T: are you kidding me? How could he behave like that?
B: it is true. Everyone kept looking at him. It was so embarrassing as I was sitting right next to him.
T:what a shame! Didn't he realized that?
B: I have no idea. He seemed to enjoy the dinner very much.
T; maybe he should really something about eating etiquette.
B: oh, he really should.

晚上我们要一起出去吃饭,贝蒂,你一块儿去吗?
我不太确定,要先看一下我的安排.你们去哪儿吃饭?
哦,杰克预定了星期五餐厅.
杰克?
对啊,就是研发组的杰克.怎么了?
我再也不会和他一起出去吃饭了.
为什么这么说?
上次我们一起去史密斯家吃晚饭,太可怕了.他吃饭根本就没规矩.
真的吗?
他吃饭时发出很大的声响,嘴里塞满了吃的却说个不停,喝汤时还弄出很大的声音来.
你在开玩笑吧!他怎么能这样呢?
真的,当时每个人都在不停地看着他.我正好坐在他旁边,觉得特别尴尬.
真丢人!他自己没有意识到吗?
我不知道,他看起来吃的很开心.
或许他真该学学餐桌礼仪了.
是啊,他真的应该学学.
