Man, this just brings back a flood of terrible memories, the damage and abuse to my car, the appointed men avoiding the hard service work, the pointless driving around, but I have to say I never once experienced anything as bad as that.
One of the most common issues was mothers who'd drop their kids off at the kingdom hall for field service as a substitute for day care and would make looking after them the congregation's problem. When I was a 17 year old pioneer I'd often find myself out in service with 3 or 4 children. Can you imagine having a teenager and four elementary school aged kids knock on your door peddling religious literature?
Another issue was people simply not showing up when field service arrangement had already been made. Early morning service was quite popular in my area. We would typically meet at 6:00 a.m. and half the time the people I'd made arrangement with simply wouldn't show up, no last minute cancellation call or anything.
