My group got the restaurant bug; it seemed to happen when two of us both spoke to the original Fred.
After restarting, we made a point of avoiding any overlap. One player talked to the first Fred, and completed all of the dialog boxes. Then the next player did the same to the next Fred, and so on. That worked.
