Alert, agile and at times miffed, he constantly moves around and transacts money in small denominations. The transactions are at times simple and sometimes complex. In some cases he asks the other parties to complete the transaction as what he has to return back is provided by another. People do not form a queue in front of him to complete their transactions. They hurry and thrust the money from all sides to complete it as fast as they can. Based on the time and crowd his transactions multiply. He has to do his computations in split second and respond. No doubt he is a counting wizard for he has no calculator or any other aid for assisting him in his calculation. His other tasks involve blowing the whistle, crowd management- asking people to move forward, asking gents seated in places reserved for Ladies to get up and also finding the seat for a senior citizen. The space between his fingers is filled with the most important item for his job. Now the items are themselves stored in an electronic device.
May be one day commuters would press a few keys from their mobile and the device in his hand would send back an eticket to the commuters mobile. Then there is no work for his brain.
