Supposedly we couldn't count our drive time unless we "punched in" with an official ringing of a doorbell.
I remember the "scandal" when the elders discovered that a couple of pioneer sisters in the congregation were in the habit of doing one "return visit" before the meeting for field service, so they could start counting their time early. What sneaks! Is that allowed? The debate raged on with a feeble persistence of people with nothing better to talk about.
