Here's a couple of suggestions:
- Just keep telling him that dinner will be ready very soon now! Tell him all the special appetizers, the plentiful meats and casseroles, finished off with the sweetest deserts he will ever taste. And keep him waiting the entire week until he has to leave to go mooch off the next congregation to preach his empty promises of "paradise very soon now".
- Tell him that you're prayerfully relying on Jehovah to provide the food. After all, if Jehovah could help some dude find a leak, as described in the WT broadcast this month, surely Jehovah could arrange to feed his faithful preachers by arranging for a pizza delivery driver to crash into a Chinese food delivery driver in front of the KH, right? Not only could they get free food from the wreckage, but they could count their time witnessing to the crash victims about how doctors have evil worldly educations, and how they should refuse blood therapy based on the dietary restrictions attributed to a Bronze Age god, and if they die now as nonJWs they have the privilege of being resurrected in a Panda Petting Paradise after their families have been slaughtered in armageddon for not being JWs. If that grizzly scenario isn't in harmony with jehovah's will, what is?
