People of an older generation and more working class background here still refer to dinner as tea and in some rural parts lunch is still called dinner.
I also live in California and know & have know many people from SF (where gaobest lives). Never once have I ever heard anyone use the word luncheon unless it was several people and under a more formal or business setting. Even then it is rarely used...more likely "I met some friends for lunch" or " I scheduled lunch with a client".
