$$$ - For real ministry or for church machinery?
My father was very thrifty yet very generous. He was a teacher and administrator at several Christian colleges in the South. On Sunday's he was a guest speaker at local churches of various denominations. He would often take his wife along to sing and his children to listen. The day was a change of scenery from the ordinary and a chance to meet some new people - always welcome and memorable, too.
Without any discussion, after the meeting was over, someone would give Daddy a check or an envelope containing a check. He would quietly endorse it, fold it and leave it in the collection plate...
