2017年杭州有几个区:在西方朋友们一块儿就餐时是不是谁点菜谁付款

It depends. Usually if you invite someone to dinner and you are the host you are expected to pay, unless you tell them in advance you will "go dutch" and split the bill 50-50. Sometimes you will agree somebody will buy the food, the other person will by the drinks. If it is a business lunch you would always pay for your customer. If a family goes to dinner usually the father pays, unless the children are older and working then they might pay.

Note that not all westerner's will pay even if they invite you, so I always make sure I have some money in case they expect me to pay for myself. This is not polite but some people do this.

Most commonly I think good friends will usually "go dutch" and split the bill 50-50. However sometimees you will agree that one time you will buy dinner, and the next time the other person will buy dinner.

Usually if you are a man and you have a girlfriend you will always pay for her meal, but some people also will split the bill or take turns paying, especially if the woman has a good job.

邀约的人付款
补充： 所以如果是老外邀约了， 你就不要抢了。

不是的 一般来说应该是AA制

但可不一定是邀约的人付款啊 美国人有时让中国人感觉到“不太讲究”的就在这里 即使是他提出要请你吃饭 如果你准备付钱了 他也不会像中国人一样抢着付 你要付就你付好了...

应该给付各的，实行AA制，这样能得到别人的尊重！！！

chentiangemalc is right, usually everybody pays for themselves unless they told you otherwise before hand. Especially like casual dinner with friends you pay for yourself by default.

When a guy is having dinner with a girl. you can tell how long they have been dating just by how they pay:

1) If the guy pays the bill without checking, they just started dating each other.
2) If the guy checks the bill carefully, and then pays, they have been together for a while.
3) If the guy hands the bill to the girl without looking at it, very likely they are married.

不一定。那要看看你跟他熟不熟。他要你就给他就是了
