Efficient..Productivity?

This is to show that we need to employ AT LEAST 4 person to collect the heavy coins in the parking meter.

Such hard work is distributed with the following task; 1 person opening the meter & make sure the meter is not closed; 1 person collecting the heavy coins from the meter to the mobile collector; 1 person pushing the heavy mobile coin collector; and 1 person to make sure that the meter is open, the coin is collected, the mobile collector is pushed.

This does not include the parking meter repairman; whom always come and repair the meter after you PARK the car and go to work. Not forgetting the parking authorities (comes in pairs on a bike); whom always come to summon your car soon after the faulty meter is repaired.

Come to think of it, the summons collected is to pay the salary of the 4-6 staffs involved..
