I want to know the answer to the following question:
In what decades did class distinctions break down in Britain?
All the background I'm provided with is that "With the blurring of class divisions in the 1960s and 1970s,[citation needed] the distinction between the saloon and the public bar was often seen as archaic,[citation needed] and was frequently abolished, usually by the removal of the dividing wall or partition.[citation needed]". Is that enough to answer the question?
