Since employees are usually the first point of contact with customers, McDonald's recognizes that it is important to fully train its employees for good customer service. McDonald's creates a customer friendly atmosphere. Inseparability The inseparability characteristic of a service refers to the fact that services are produced and consumed at the same time. They cannot be separated from their suppliers, be they people or machines. The McDonald's employee is part of the service and so is the customer. Both together influence the service offered.
