Greer decision is related to the fact that quality of services is inconsistent/variable. When there is a service such as getting your nails done, there can be inconsistency with the work due to human error. Not everything done by a human is perfect and typically varies each time the work is completed. There are six types of service characterstics and they are: lack of ownership, intangibility, inseparability, variability, perishability, and user participaton. In this scenario, variability is the best characteristic to describe the inconsistency of Greer's manicure.
