“再来一份”是Can I have another one吗？

当在国外吃到了自己喜欢的美食，一份不够，还想再来一份的时候，用英语要怎么说？

Two foreign visitors enjoy leisure time at a restaurant in Yangshuo, South China's Guangxi Zhuang autonomous region, on July 5, 2020. 

很多小伙伴可能脱口而出：Can I have another one？

但当店员听见这句话，他可能会急忙跑过来问你Are there any problems? Can I have another one其实是表示对食物不满意，需要更换一份。而“再来一份”的正确表达则应该是Just one more, please. 例句：Excuse me sir, one more apple pie, please.

您好，再来一份苹果派，谢谢。

如果是想询问别人要不要再来一份，这个时候应该说Would you like another helping? 此外，还可以用second
