Hi Gang-
I used to work at the accounting department at the assemblies where people would buy the food tickets and use those to purchase food. The money made from the food was used to help pay for the expenses of using the assembly hall. That is why the Society was "encouraged" people to purchase food and eat at the assembly. I suspect they changed to the donation arrangement for food to avoid paying sales tax and when the people eventually quit donating enough to cover the cost of the food they quit providing the food. In addition, it was not uncommon for us to hold off counting some of the money towards the end of the assembly so as to show a deficit that could be reported to the assembly so as to motivate people to give more money.
Also, at the circuit assemblies it was always interesting to see the District Overseer show up and get his money from us. :)
One year I worked in the accounting department for an international convention in New Orleans. At the end of the day, we would make a deposit of the days receipts. I would drive the car and we would be followed by a bunch of armed police and security guards to the bank. It was quite a production. :)
