At their first meal together, the Frenchman said, "Bon appetit!"
"Santa Ji," said Santa.
Before the next meal commenced the performance was repeated.
"Bon appetit," said the Frenchman.
"Santa Ji," replied Santa.
After this continued for three days, Santa got fed up, and told a fellow traveller about it.
"He tells me his name is Bon Appetit and I tell him my name is Santa, and then at the next meal, we start all over again."
The fellow traveller laughed and explained to Santa that the Frenchman was not introducing himself and that 'Bon appetit' meant "Good appetite", or "I hope that you enjoy your meal!"
Santa breathed a sigh of relief on receiving this information. Next morning, at breakfast, Santa greeted the Frenchman with a, "Bon appetite."
The Frenchman nodded politely and said, "Santa Ji."
