Many of the dubs in my area bequeath large sums of money to the WT in their will. Many years ago, a sister willed her home and her insurance policy to the local congregation when she died. If I remember correctly, the WT made the congregation sell the property ASAP. The money was used to renovate the KH (it was and still is a money-pit, large building expensive repairs, the just got the OK to sell the dump).
The biggest grab in my area is by the CO's in the form of the 'green hand-shake'. Everybody participates. The widow wanting attention, the ambitious MS, the Elder wanting to give CA/DA talks, the pioneer wanting a part on the program, the brother owning a business wanting to do some 'paid' work at the KH and the general brown-noser. It's sickening to watch all of this play out. The CO's just revel in the attention and don't discourage it.
