Mouret and Bourdoncle crossed the cashier's office and the invoice room and when they passed into the third office the young men there, who were laughing and joking together, started with surprise. Mouret, without reprimanding them, thereupon explained his scheme of giving them a little bonus for each error they might detect in the debit notes; and when he went out the clerks, quite cured of all inclination for idle laughter, set to work in earnest, hunting for errors. On reaching the ground-floor, occupied by the shops, Mouret went straight to pay-desk No. 10, where Albert Lhomme was polishing his nails, pending the arrival of customers. People currently spoke of "the Lhomme dynasty," since Madame Aurélie, first-hand in the mantle department, after helping her husband to secure the post of chief cashier, had further managed to get a pay desk for her son, a tall, pale, vicious young man who had been unable to remain in any situation, and had caused her an immense deal of anxiety. On reaching his desk, Mouret, who never cared to render himself unpopular by performing police duty, and from policy and taste preferred to play the part of a benign Providence, retired into the back ground, after gently nudging Bourdoncle with his elbow. It was Bourdoncle, the infallible and impeccable, whom he generally charged with the duty of reprimanding. "Monsieur Albert," said Bourdoncle, severely, "you have again taken an address wrong; the parcel has come back. It is unbearable!" The cashier, thinking it advisable to defend himself, called as a witness the assistant who had tied up the packet. This assistant, named Joseph, also belonged to the Lhomme dynasty, for he was Albert's foster brother, and likewise owed his place to Madame Aurélie's influence. Albert sought to make him say that the mistake had been made by the customer herself, but all Joseph could do was to stutter and twist the shaggy beard that ornamented his scarred face, struggling the while between his conscience and his gratitude to his protectors. "Let Joseph alone," Bourdoncle exclaimed at last, "and don't say any more. It's a lucky thing for you that we are mindful of your mother's good services!"
