I remember cringe-inducing notices read by elders from the platform instructing sisters who were preparing meals for the CO to "not over do it" and stick to plain nutritious meals, that Jehovah knew what was in their hearts so they did not need to try to impress the CO, etc..
I guess there may have been some basic sense in the "instruction" but it was phrased and delivered to the entire congregation in such a condescending and almost a chiding manner. As I sat there listening to the brother intoning at some length about this issue, I remember thinking, "The nerve! They ought to be bloody grateful that sisters are even volunteering in the first place, let alone being told how and what to prepare!"
Of course, I never said anything at the time!
