I just want to ask what is the impact of using お帰りなさい on someone who just come back from a business trip? well to elaborate a little, we have a Japanese employee in our company, and one of my colleague say that to him, sometimes she is using お帰りなさいませ on him. While my other colleague are saying like welcome back on him; So I am just wondering what is its impact on him since every time she said it to him he seems happy and sometimes laughing.
Thanks a lot
