This person probably goes to the office and sits in her own private room by herself, because she can't focus with the loud plebs on the big open office floor
That rigid sense of time brings back memories. As a kid you'd have to wait on some corner to meet with friends and go out. Without smartphones there was no way of knowing where they were or what time they'd show up. If they were late you had to simply wait for them to show up or at some point decide to leave. All without being able to communicate anything. So everybody was a bit more flexible and relaxed about waiting on eachother.
