I have known assembly attendants who fudged the seat counts, let alone the time slips from ordinary JWs...
Hah, that is sooo true! I remember the time a DO by the name of Bartell insisted on the attendance figures being too low. He called for another count. The section captains went to their assigned attendants and told them to meet, they were told to count any one and every one in sight, especially babies because sometimes they're on their parents' laps or they're in a carrying seat in the isle and hard to see, and he winked for a lonnnnggg time.
Sure enough the numbers from just about all attendants reflected higher numbers... unfortunately the new count was now way up high, by several hundred.
