Rocky Guide Service provides guided 1-5 day hiking tours throughout the Rocky Mountains. Wilderness Tours hires Rocky to lead various tours that Wilderness sells. Rocky receives $1,000 per tour day, and shortly after the end of each month Rocky learns whether it will receive a $100 bonus per tour day it guided during the previous month if its service during that month received an average evaluation of "excellent" by Wilderness customers. The $1,000 per day and any bonus due are paid in one lump payment shortly after the end of each month.
