In the exchange, published in Hansard, the member for Christchurch, suggested cheaper prices to "ensure maximum utilisation" of the dining rooms on Monday, Tuesday and Wednesday evenings.
He was told by Liberal Democrat MP John Thurso that a variable pricing structure would return, including offers and promotions for the dining room.
"I thank my honourable Friend for that response. Last week, I dined on all three nights in the Dining Room and almost nobody else was present, but the service was fantastic because there were three servants for each person sitting down," Chope replied.
This prompted the outburst of "servants?" from other MPs in the house.
"Exactly," Chope continued.
"Does my honourable Friend think that one way of engaging Members who do not use the Dining Room would be to offer them much cheaper rates when there is an opportunity for them to come along?"
Labour MP for Wallasey & Shadow Leader of the House of Commons Angela Eagle said on Twitter: "Tory MP Christopher Chope let's the cat out of the bag by referring to HoC waiters and waitresses as 'servants!' #HoCquestions"
