When exactly should a stipend be given?

[need_to_know]

In this answer, Michelle Arnold said that:

There are times when priests are given a stipend for the celebration of certain sacraments – notably baptisms, weddings, funerals, and memorial Masses.

I thought that a stipend should/could be given simply if a priest offers an ordinary Sunday Mass for a particular intention which a parishioner requests it be said for.

Generally speaking, that is basically the definition of a “memorial Mass.”
