Well I suppose a very junior clerk, the first job I was given was, well it's unheard of in this day and age but what they had was what they call a bundi clock and there every driver and conductor had got a key that was inserted in this clock and on it was his personal number, well  when he reported for duty, he inserted this key into the clock, turned the handle and stamped on to a piece of paper, a roll of paper, his number and the time he reported and the next day it was my job to go through and record from this piece of paper how many minutes they were late f reporting for duty and if they erm were more than, I think about three or four minutes we had to send them a memo telling them, that's how things were in those days that people were, they toed the line or else.
