I have to admit I was a bit scared when I read this too. My introvertness makes me want to run from stuff like this. However I do have to say that there should be some effort to greet the new person. I had one job where I was sat in a cube and no one around me me said hello. I had to reach out and they were so dispirited I got a lukewarm response. It was a chilling effect for a first day.

Oh and I could not do anything with my machine since it was not set up.
