Daisy has been warning Mrs Patmore that the wood stove is not functioning properly. There is a big dinner party for the evening and the guests are arriving. In the kitchen, all of a sudden Mrs Patmore is panicking because no food is ready, nothing has been cooked because the oven is not working. This is patently ridiculous. For a party that size, the kitchen would have been cooking for 2 days and 90% of the food would have been ready when the guests started arriving.
