Applauder

“When Selius spreads his nets for an invitation
To dinner, if you’re due to plead a cause
In court or give a poetry recitation,
Take him along, he’ll furnish your applause:
‘Well said!’ ‘Hear, hear!’ ‘Bravo!’ ‘Shrewd point!’ ‘That’s good!’,
Till you say, ‘Shut up now, you’ve earned your food.’”

--Martial, The Epigrams (85 AD).
