On an average each letter takes nearly 3 hours from start to reach the dispatch section. Furthermore, the dispatch section takes 5 hours on an average to despatch the letter on the same day and 20 hours if the letter is sent after 2.00 PM, as the postal service is once a day. Depending on the urgency of the subject matter, a letter takes a short cut to the dispatch section, which it occupies the same time to be sent.
In spite of all this, there is no guarantee whether the letter dispatched has reached the recipients. Last but not the least, it is impossible to have a central repository for future reference |
