Apologizing. When they screwed up, one way or another, they owned up to it and said so to as many people who would listen. This kind of culture is infectious, in the good way. Be respectful of calendars. When I block off some time to focus on a hard problem, they don't interrupt me. If something does come up, they cautiously IM, "when would be a good time for an important interruption?" and nothing else. No phone calls, no swinging by my desk, no details of the issue, etc.
