Xenophon, Cyropaedia

He used also to honour with presents from his table any one of his servants whom he took occasion to commend; and he had all of his servants' food served from his own table, for he thought that this would implant in them a certain amount of good-will, just as it does in dogs. And if he wished to have any one of his friends courted by the multitude, to such a one he would send presents from his table. And that device proved effective; for even to this day everybody pays more diligent court to those to whom they see things sent from the royal table; for they think that such persons must be in high favour and in a position to secure for them anything they may want. Moreover, it is not for these reasons only that that which is sent by the king gives delight, but the food that is sent from the king's board really is much superior in the gratification also that it gives.
