Samantha Green (the same Samantha we met at the end of Chapter 3, page 79) owns and operates Twigs Tree Trimming Service. Recall that Samantha has a degree from a forestry program and recently opened her business in St. Louis, Missouri. Her business consists of many one-time operations (e.g., removing a tree or stump), as well as recurring services (e.g., trimming customers’ trees every year or two). When business is slow, Samantha calls former clients to remind them of her services and of the need to trim their trees on a regular basis.
