With gas prices staying up, I wonder how that is going to affect the ministry. I wonder if people are going to be more inclined to do more door to door, since that usually involves less driving around than calls do. And if they are going to spend less time warming up or cooling down, since it takes gas to run the engine to heat the car or to run the air conditioner. This could also make people more efficient in calls, since they might have a group of them in one area to cut down on driving around.
On the other hand, with higher gas prices it might dissuade people from going out as much in service. Each time they start the car and make the trip to the Kingdumb Hell, they waste gas. Fewer trips means less gas wasted on this. And that might make them reluctant to call back on people in isolated areas and in mountainous regions. Those people might see less of the Witlesses.
What you might see more of: Door to door in areas where many houses are together. Meaning--if you're in the city or a village, you will expect the Witlesses at your door more often but in rural areas, less of them. People coming out less often but staying out longer to cut back on unnecessary trips to the Kingdumb Hell. More calls that are clustered together. Shorter warming-up and cooling-down breaks and longer coffee breaks (as long as the Tower doesn't ban coffee: this observation might lead them to ban it altogether). More days where no one shows up for service.
You might see less of this: Calls that are scattered around the city or town. Long times where the vehicle is running to warm up or cool off. That van that always parks outside the Kingdumb Hell running to raise false hopes of a no-show, only to dash that just before the program starts. Calls made without making a cell phone call to make sure the person is going to be home. Rural areas worked where houses are a long distance apart.
You might also see more street work, parking lot work, and phone and letter witlessing. Those use only the gas it takes to get to the spot, and then you sit there and wait until someone is trying to get through and then you sprint to get to them before they get away. They will likely use the phone and letters to save on gas money while still getting their time in. I doubt they will start spamming people on cold calls since someone receiving one of those spams could send a spam in reply with a link to an apostate Web site or apostate material.
One more thing: Ted Jaracz might lead his cohorts to reinforce that this message is so important that, if gas goes up to $10,000 a gallon, that we should waste it in the misery. So what if it creates a serious hardship? This work is so important that you should just do it anyways. Even if there is a national shortage, you should waste it because this work is the only work that puts money and power into that group of humanoids in Brooklyn. And they don't have to pay for the gas you put in your car to waste going around in the misery, so they are going to tell you to just do it.
