When Myself and Arch co-conspirator chaps refer to 'making an exhibition of ourselves', it is not bad behaviour in public, merely one of exceptional gluttony.
A fine example is ordering a 'Grand-Gourmand' meal in our favourite restaurant in Cherbourg and eating every single morsel of the 9 course feast. With bread. And a bottle of Burgundy each worth the price of the meal.
We leave the throwing of bread rolls and loud miscreations to Mockneys, Grammar School types and Champagne Socialists.
