Public toilet and bashful usage of dining room

For years, I have been searching for the title of a film that I watched years ago. All that I remember was people were very comfortable hanging out in the toilet but had to bashfully ask others to excuse themselves when going to eat.

No one seemed to recall this film including the friend who watched it with me.

As time goes by, I am starting to wonder whether it really was a film I watched.

Though, voila, today I found out it really existed.

It was Le fantôme de la liberté or The Phantom of Liberty by Luis Buñuel.

Public Toilet

Private dining

Engaging in unspeakablely shameful act called eating in isolation.
