I believe I do have a timeline of events that you might find enlightening.
The Wilkinson family – Jerry, Hilla, Myra, Deborah and Benji – are meeting Jerry’s parents for dinner.
Upon arriving at the restaurant, Jerry realises that it is a posher venue than they were expecting. He reluctantly enforces “Gale Force 5 table manners” on the children.
As compensation, Jerry promises that they will keep the meal to a short two courses and declares open season on the pudding menu. Since Deborah doesn’t like pudding, she is offered the option to have a starter for pudding instead.
Jerry counts them all down to the start of the enforcement of manners. During the five second countdown, the family make wild and rude noises. They stop immediately when he reaches zero and all commence best behaviour.
