Louise is disgusted by the fact Charlie's bar has turned into an establishment that "exploits women", because Charlie has hired scantily clad women, and she has the support of both Florence and Helen when Helen learns that Tom is one of the financial backers. However, in the episode "Put It On" (S7E6), Louise, Florence and Helen spend the evening at an all male strip club, a business that undoubtedly exploits men.
The title is a cultural reference to the television series, "Charlie's Angels".
