The same day? I wonder if there's another reason.
I have been keeping up with the religion constantly asking for money, taking KH savings accounts, etc...But back when I was attending years ago there were at least two stories I heard about brothers who brazenly embezzled significant amounts of money! I wasn't surprised when I heard this because I knew some JWs are worthless and think they're not going to be prosecuted.
Maybe the religion does not even TRUST the local JW brothers to keep their hands out of the till so they don't want a large amount accumulating. So, they want it right away.
