30 years back,one of my colleagues  was working as a Goods Clerk in Railways and we were to charge for storage of goods, if they remain in the custody of Railways, beyond the permissible free time after they are unloaded from wagons,which is known as "Wharfage charge."   On every Sunday morning the details of the stock available will be recorded in a Register called "Sunday Stock",got countersigned by Station Master and the register will be linked with unloading/delivery Registers for correctness.     Whenever the periodical Auditor lands in the station, for check, he would immediately draw a line in the register and record the stock position in (Red and White;like black and white, they use red.)and strike at the total,duly endorsing the number of articles in words. This also will be countersigned by clerk and Station Master.

On the "Dooms day" an Auditor landed and commenced his job. Unusually, he took a paper and jotted down the  details of packages which were accruing "Wharfage", keeping them off the Record of Sunday Stock.  Then he started bargaining with the "Carting Agent" for a bribe for non-removal,though delivered.  Those were cement bags in few thousands.  They arrived at some mutual deal.  The Auditor was not aware of the Agent,who had only one truck and the driver used to be missing many a times. 

Next morning there was a news that the Vigilance Squad had arrived at the next but one station and a raid was going on.  Perhaps their next trap might be our station.  The Auditor was in a fix.  The Agent never turned up to remove the suspense stock.  The Station Master refused for any corrections on the Sunday Stock book,which was in his custody.

This Auditor made umpteen calls to the Agent requesting him to remove the goods immediately,failing which the Auditor couldn't escape from the clutches of Vigilance people.  He even agreed to repay the bribed amount in addition to share the transportation charges.  Finally to his good luck or otherwise the Vigilance people returned to their headquarters without coming to this station and the pity is the Auditor lost a few hundred rupees by way of giving to the Agent.
