Notice to all that don't think this is actually happening. It might not be happening in your hall, but there are halls where the hounders that are handling this could have decided to confiscate the Kool-Aids from visitors in that hall without its being organization wide. Or, the hounder-hounder could have "suggested" it to the hounders in his circuit. Most people within that circuit will then think it is from the Society because all the nearby congregations are doing the same. But, outside the circuit, it might not be happening.
Or, perhaps there was a directive from the Society to reclaim the Kool-Aids from visitors and not all the hounders are taking this directive seriously. This could actually happen if the hounders in one congregation or several contiguous congregations feel that it would be a lousy idea to reclaim Kool-Aids from visitors despite directive to do so. Either way, it is not uniformly enforced. Nor do I expect it to be until all the hounder-hounder-hounders in the country are informed to strictly either take them back or to not take them back, and then it gets through all the hounder-hounders and then all the congregations. This could take quite some time to filter all the way down. But, then we know how inefficient and ineffective that organization really is.
