I've read about individuals on this forum who would "pad" or completley fake their hours, or who were in charge of the monthly congregation report and altered the entire groups report in order to stay in the good graces of the Circuit Overseer.
Then there's the whole business of having two people at the same door or an entire car group waiting in the driveway, all counting time while one person talks to an occasional householder. The whole thing is such a joke....don't waste your energy feeling bad about it. Sometimes it's enough just to get by as best you can.
