It's a Living S01E13 - You're Not Old, You're Fired

Following a management evaluation of the staff at Above The Top after dinner serve one night, Nancy informs the girls and Sonny that she is being let go by management for undisclosed reasons, which shocks everyone of the staff.  She also tells the waitresses and Sonny that Lois is to be the new hostess at Above The Top from now on.  The next evening, Lois is having a hard time as hostess, as reservations get mixed up and frustrated customers leave the restaurant after waiting more than an hour.  The next day, Lois informs the girls that she found out that Nancy got fired because of her age and that she wants Jan, Dot, Vicky and Cassie to join her as a united front to see Nancy and tell her that she must fight Mr. Steadman, the head of management, to get her hostess job back at Above The Top.  After leaving the restaurant, the girls arrive at a greasy diner called Marz, where they find Nancy working there as a waitress.  Lois and the girls try to convince Nancy to come back to Above The Top and get her old job back, but to no avail.  Later that evening, during dinner serve, Nancy arrives at Above The Top, disheveled and dirty in her waitress uniform, where she confronts Steadman (who just had a talk with Lois over the hostessing situation) and tells him that if he doesn't get her job back, she will sue management for age discrimination.  Seeing that he has no other alternative, Steadman immediately rehires Nancy as hostess of the restaurant.
