O'Donnel's, a new supermarket, has just opened in Pixley. Sam hasn't had a customer since it opened. Even Uncle Joe goes to O'Donnel's to check it out. While there, Joe manages to annoy Mr. O'Donnel. Kate and the girls are still loyal customers of Sam's. Joe thinks that Sam should modernize his store. Sam starts to have anxiety attacks and doesn't recognize Kate and Betty Joe. Kate and Doc Stuart convince Sam to take a two week vacation. Kate and the girls agree to look after the store for him. They decide to reorganize the store. Kate briefly leaves Joe in charge of the store and he puts in an overly large grocery order with salesman Jack Hull. Charley and Floyd bring a train full of groceries to the store. Kate is furious with Joe when she learns it can't be returned. Kate winds up at the lodge where Sam is and she is just as dazed as Sam originally was.
