Narrative:

When the piper asked myself (working in the unicom room) for the airport advisory, winds favored runway 13. After the piper taxied to runway 13 and performed run-up checks, the winds had shifted to favor runway 31. As the piper taxied onto runway 13, I gave the advisory to the cessna that was at the time 45 degrees to left downwind of runway 31. The piper pilot immediately stated he was departing from runway 13, and just after that, the cessna pilot stated he was on 'left downwind, turning base, looking for the piper.' when the piper lifted from the runway, the cessna had started his turn for final approach. Each pilot stated they saw each other and at about 400-600 ft AGL, each aircraft altered course to the right. The piper made an early turn out of the pattern, and the cessna proceeded to land on runway 31. Myself and another airport employee witnessed this incident.
