It is all about putting hours on a time slip. If the Gibbering Booty said "Friends, there is no longer a requirement to count hours when you go in service," the bottom would fall out of the "life saving" work in about 3 months.
What is completely absurd, crazy and stupid is the Witlesses think they have a life giving message that must be given because the end is so sooooooon. If a Witness saw smoke coming out of his neighbors house would he stand outside his house sipping on a latte with a sign that says, "Neighbor, your house is on fire."
Those minding the carts...do they believe that all those walking by will be destroyed at Armageddon? Then why not go up to the passerbys and give them a warning message? Why not engage people in conversation. Why goes stand there advertising for Starbucks or updating Facebook, or telling the latest gossip in the Kingdam Hulls? Because they don't really believe it and it is just putting in hours which is much easier than going door to door where you may actually have to talk to someone if you knock on the door too loud.
