Ladies' Lounge Meaning

(Australia) A room in a pub or hotel, separate from the main drinking area, in which drinks are served; originally a place for women to drink in when not welcome or not comfortable in the traditionally male-oriented public bar, and latterly a more genteel area than the public bar. [1]

Example: Used other than as an idiom: see lady,‎ lounge.

Dissent or satire — especially where these matters were concerned — was unthinkable.
