I think the idea is a nice one, to do something for the new employee , to make him comfortable, and feel at home. But honestly, the streamers is a bit much. We must remember that this is a professional environment but that we spend a lot of time here , so he must feel comfortable. I think that the bagels, juice, coffee, and fruit thing sounds appropriate. That way, it can have a meet and greet atmosphere to it, where you get to introduce yourself and different members of the team. Being the new person in the office before myself, I was more concerned with how I was treated once I started to do my job. So keep a light atmosphere, yet professional. The streamers seem a bit personal for someone that you do not know . But if you greeting him with light food and drinks, lol, I think he would appreciate that much more. Then, once you get to know him, and know his likes, you can do the streamers thing, for like a birthday or something. This is a very nice idea, and remember, its nice to be nice,,, because its nice!!!
