英文里“请客”如何表达

　　最近我很大方（generous），到处请客。在英语里“请客”都怎么说呢？

　　It's on me. 我请客。

　　Hey, don't worry about it folks. It's on me. (It's my treat.) 兄弟们都放着，我来请！

　　You get the next one. 下次你来吧！

　　Don't worry about it, you get the next one. 别，这次我来，下回你请。

　　It's my treat. 今天我请客。

　　I wouldn't hear of it. 我不能让你们请客，我请。

　　Put your money away. No no no. I wouldn't hear of it. 把你钱包收起来，别呀，我不能让你们请客。

　　如果人家非要请客，那被请的人应该说什么呢？

　　If you insist, but next time it's my treat. 好吧，如果你坚持你就请吧。不过下次算我的。
