Person1: Did you see the way that Brian came to work yesterday ? Ever since he came back from that conference in Silicon Valley , he's been coming to work dressed in jeans and sweatshirts . It's like he's decided to make himself at home in his office . I don't know how long it'll take before the management talks to him about it .
Person2: He was really influenced by the way they do things on the west coast . I guess the working atmosphere is a lot more relaxed and casual in California . It comes from the information technology industry .. there isn't such a large division between home and office , so people want to work in the clothes they feel more relaxed in .
Person1: Maybe so , but it seems kind of strange , which the rest of us in white shirts , dark suites , and ties .
Person2: It's not as bad as that ... We are allowed to wear more casual jackets and trousers . Besides , didn't you hear what Brian found on his desk this morning ?
Person1: What's that ?
Person2: Management decided to give him four brand new white shirts . That's their way of telling him that his new style of dressing down is not quite acceptable .

Person2: A couple of times .
Person1: Can you go there with me ? I'd like someone who is familiar with that area to go with me .
