你食左飯未a??

要答既都俾人答左
我唔再多講
但係想講一句，中國人有禮貌一見面就問人地食左飯未做開場白黎打開話題。
但係你要明白外國人既禮儀同中國人係唔同既，所以你唔好無啦啦問外國人食左飯未。 佢地會諗：食唔食左又點？ 做咩呀？ 請我食呀？
同外國人見面，講一句：
Hi 或者 how are you 就夠。
年輕一的既或者講句：
What's up, How's going
好多野係唔可以直譯既

大多數人用

have　ｈａｄ

以上所講

你食左飯未a??---->Do you have your dinner/lunch?

Have you ate?
Have you took your meal/lunch/dinner?

well, English people don't really ask 'have you eaten yet?' as a greeting.

Perhaps, you would like to say simply,
'how are you?'
'how are you doing?'

If you want to introduce yourself,
'Hi, I'm ..... Nice to you meet you.' + shake hands

Have you ate/taken your lunch/dinner?
Use taken is more formal and polite.

Have you had your meal (breadfast / lunch / dinner)?
Have you got your meal?

如果問你食左午飯未, Have you had your lunch ?

如果問你食左晚飯未, Have you had your dinner ?

Have you eaten?

樓上一個用Have you ate一個用Have you eat香港的教育開支用到那裡去了？對不起，老人家一年交二十幾萬稅，看見這樣的教育成果，發發牢騷而已，不要見怪。香港的未來是你們的，祝好運。

Have you eat lunch yet?

你食左飯未a??
