Germans like things to be on time (at work, when expecting parcels from the post office, or when waiting for subways). This means: we love to make regular appointments. So when it comes to a project, we will probably ask for more than one meeting to discuss the status of the work done so far. And indeed, be waiting in the conference room 5 minutes earlier. So better be on time. We like to plan ahead, and the worst thing that could happen is something not running on schedule.
