Saw a great short segment in a YouTube video a year or two ago where a Watchtower minister is putting HIS money into the WBTS' collection box, with the "paying minister" comment!!
Of course every publisher is told s/he is a minister!
Put this way it really struck me for the first time that the Watchtower has a fairly clever con running in this area which their (straining) followers have yet to fully grasp.
Of course as we know full-time "volunteers" at the Bethel branches receive a modest "living allowance" and the hierarchy big wigs receive numerous free privileges including overseas travel and accommodation.
