Can anyone identify a (possibly French) film where the cultural taboos about going to the toilet and eating (not at the same time!) are reversed?
I remember seeing a scene with someone knocking on a door to an eating room, finding that someone was already in there eating their dinner, and being embarrassed, as if it was actually a toilet (restroom). They were quite happy going to the toilet together however.
Does that ring any bells?
This may actually be a TV programme, rather than a film, so I hope that's still acceptable.
One of Luis Bunuel's most free-form and purely Surrealist films,
consisting of a series of only vaguely related episodes - most
famously, the dinner party scene where people sit on lavatories round
a dinner table on, occasionally retiring to a little room to eat.
The scene you are looking for is available on Youtube.
