In this case, "that's a classic" means "that's typical/unsurprising/unfunny." It has a bit of a sarcastic feel. The speaker is referring to her job as a barista, as it is typical for aspiring actresses in Los Angeles to work as baristas or waitresses. Ex: A: What do you want to be when you grow up? B: An Instagram model or Youtuber! A: That's a classic.
