Expression of disapproval of people who talk loudly in restaurants
From the Monty Python sketch Mr Neville Shunt. The line is:
Art critic: Some people have made the mistake of seeing Shunt’s work as a load of rubbish about railway timetables, but clever people like me, who talk loudly in restaurants, see this as a deliberate ambiguity, a plea for understanding in a mechanized ethos.
