A useful, and everyday way of understanding dramaturgy (specifically front stage and back stage) is to think of a waiter or waitress at a restaurant. Their main avenue of concern for him or her is "customer service." Even if a customer is rude, waiters and/or waitresses are expected to be polite ("the customer is always right") as part of their job responsibilities. That same waiter or waitress speaks differently when going out to her/his break room. s/he may complain, mimic and discuss with their fellow peers how irritating and rude the customer is. In this example, the waiter/waitress acts a certain way when dealing with customers and acts a completely different way when with her/his fellow employees.
