请教英文的高手，在一个有很多人的快餐店，刚好有个外国人来拼台，这时目光对视时怎样和人家打招呼？假如

Answer 1

Foreigner：Have this seat got someone, and could I sit down here ?
Me：Yes,please.
Foreigner：Thank you !
Me：You're welcome.

呵呵，好像教科书啊。在国外很少这么说吧，除非是70多岁的老太太。
F：MAY I SIT HERE?
M: SURE
F: THANKS.
M: NO PRONLEM.
然后个人吃个人的饭。

Answer 2

打招呼很容易，说声HI就可以了，要展开话题可以从天气开始，一般外国陌生人之间都这样，如果这个外国人还友善，可以谈一谈食物，从哪里来等等你想谈的

Answer 3

Hi! How are you? Are you new to _____________(name of the city in China)?
The other person answers.
How long are you staying here for?
ANSWER (remember to look for clues to see if the other person is busy or not)
(You can pretty much talk about anything now)
I can show you around if you are not familar with this place. (smile) And I can teach you chinese, if you teach me English.(laugh)
(I am sorry, but I am very bored when I wrote this, so treat this as a joke...)

Answer 4

他会说：你这里有没有人，我可不可以坐这里，你就说，yes,please.
他说谢谢，你就说,you're welcome.
还能说什么？你不吃饭了？干嘛老跟人家对视啊？
呵呵

追问

呵呵，我说得不清，其实不是老跟人家对视，而是人家捧饭过来时本能的看一下他，而这时他刚好也看到我看他，仅这一刹那目光接触，不过一般他会先开口问吧.

另外：我想译一下整个对话，你帮我看一下，谢谢！不过我很菜，还是学习初期，可能译成中式英文，见笑了。
