Few companies take the time to estimate the value of a good customer (and often spend little effort to keep one). Suppose that a customer at a restaurant spends, on average, R per visit and comes F times each year (for example, if a customer purchases once every two years, then 1 F-=-0.5. The restaurant realizes a gross profit margin of M (expressed as a fraction) on the average bil for food and drinks. In addition, the fraction of customers defecting (not returning) each year is D.
