Final answer:
The text describes Rodney Rothman's participant observation experiment at a 'dot com' company but does not mention Ray or who visits his office, hence we cannot directly answer the student's question with the provided information.
Step-by-step explanation:
The question pertains to who appears at Ray's office and what Ray is doing at that moment. However, the provided reference text does not explicitly state who this 'Ray' is nor who shows up at his office. Instead, the text discusses Rodney Rothman, a comic writer who conducted a participant observation by infiltrating a 'dot com' company's office under the guise of being an employee. During this time, Rothman engaged with real employees, claimed a desk, and even attended a meeting, all without having been officially hired or questioned about his role in the company. The purpose was to get an insider's view of white-collar work and it resulted in an article titled 'My Fake Job.'
