Tiny Office Process

You are a manager in a small division. Your task is to ensure that the processing of documents goes smoothly, day after day.
Visitors enter your office - and you need to receive a document, process it and issue it. Each operation is done by a separate subordinate of yours.
However, your workers may fall asleep. If the visitor waits too long for service (he becomes evil), you will be fired (game over). If the queue gets too long (they become evil), you will be fired (game over too).
To wake up an employee, you must gain strength (!) by resting in your executive chair.
