Many years ago we had my Niece and Nephew staying with us for the weekend, we took them for a day out,finishing with a meal out.
They had been fighting and squabbling all day, and as the meal was put in front of us, Mr S gave them a good talking to, telling them to behave themselves, eat their food nicely and not make a show of themselves.
Mr S then put his fork into his fish, which promptly shot off the the plate and across the table with peas and chips flying everywhere.
There was silence for about ten seconds, then we all just ended up in fits of giggles.
The children have grown up now, but they have never forgotten it.
