Incense: was used at the principal sung Solemn High Mass on Sunday, and if you were allergic either to the incense or to the seasonal flowers that were always allowed to stay on the altar until they were wilted, tough luck; you sat in the back and went to a different Mass and blew your nose appropriately in the lobby, not in the sanctuary if you could help it. Incense was not used generally at low Mass, early in the morning. Saturday night vigils before Vatican II were unheard of.
Intinction: Never even considered. The faithful received the Body of Christ only, and then on the tongue, and then on their knees at the altar rail, frozen stiff like a statue, with a paten held below the chin by an obliging altar boy. Only the celebrant partook of the Precious Blood, maybe shared with the server.
