Sirach 32:11

Ben Sira, Ecclesiasticus

9 Among the great do not act as their equal; and when another is speaking, do not babble. 10 Lightning travels ahead of the thunder, and approval goes before one who is modest. 11 Leave in good time and do not be the last; go home quickly and do not linger. 12 Amuse yourself there to your heart's content, but do not sin through proud speech. 13 But above all bless your Maker, who fills you with his good gifts.

Clement of Alexandria The Instructor 2.7

Paedagogus

Eat, it is said, like a man what is set before you. Be the first to stop for the sake of regimen; and, if seated in the midst of several people, do not stretch out your hand before them. You must never rush forward under the influence of gluttony; nor must you, though desirous, reach out your hand till some time, inasmuch as by greed one shows an uncontrolled appetite. Nor are you, in the midst of the repast, to exhibit yourselves hugging your food like wild beasts; nor helping yourselves to too much sauce, for man is not by nature a sauce-consumer, but a bread-eater. A temperate man, too, must rise before the general company, and retire quietly from the banquet. For at the time for rising, it is said, be not the last; haste home. The twelve, having called together the multitude of the disciples, said, It is not meet for us to leave the word of God and serve tables. If they avoided this, much more did they shun gluttony.
