Note 11 — Chapter X · DEPORTMENT AT A HOTEL, OR AT A LARGE BOARDING-HOUSE.
Reading edition
It is customary with professional or public musicians, when in private company, to volunteer a song or a piece; knowing that, out of delicacy, no one will ask them to give a gratuitous specimen of the art by which they live. This is polite and proper. It is always duly appreciated, and adds to the popularity of the performer.
