I cannot speak for other countries, but it has become evident of late that more and more talks are being done by Presiding Overseers at KH's (especially in the West Midlands) and they are making it quite clear that they are expecting £3 from every publisher (per day) who visit the Dudley Assembly Hall, West Midlands to contribute towards the upkeep of it.
The quote from the PO's who have done this talk have said that "it is expected that each Publisher will put £3 into the box on each day".
What do you think of that then? As the world hits an economic breakdown the JW's seem to maximising their income from struggling families.
Dudley Assembly Hall holds about 600-700 people. I'm sure people are capable of doing the maths.
So much for voluntary contributions !!!
