why must they make it such a hassle?

after a long wait, finally saw on the papers that my giro-linked ezlink card could be exchanged for the new card. so i purposely walked that extra 30m to the control station only to realised it could only be exchanged at the ticket sales office at certain stations. ahhh...why so troublesome? imagine if you do not make use any of the stations with the ticket sales office, you still have to make a special trip and waste some transportation fee and time just to exchange the card! and it's not our own choice to make the exchange. really think it's quite ridiculous!
