My take is that it's a messy day today, and they were at the local KH making phone calls - to get their 'time' in for the day.
I'll bet that right next to the KH telephone there is a "donation" box where the publisher puts in the "suggested" 30 cents for making each phone call. Most will make three calls, donate a dollar, and give the 10 cents change away for free.
(Used to be you did telephone witnessing from your own home. Shut-ins and handicapped that are in good standing still do it this way, I believe.)
Still pains me how they extract so much free labor and money from really good people who really don't know what's going on.
For example: How many of them don't know that all the money they contributed for the kingdom hall does not belong to their congregation? In every congregation all the elders of the kingdom hall have a secret meeting which transfers ownership of the land and building of the kingdom hall directly to the WTS without pre nor post congregation notice of what they have done!
When I heard and confirmed this "truth", I stopped contributing. I didn't consent to it and I figured the WTS can pay for their own mortgage and maintenence for this under-the-table action for a kingdom hall we were fooled to believe is ours but that is secretly their's paid with our money.
