How many student concession pass holders agrees that's its unfair to calculate based on number of taps? The top winner for last weekend was 2006 taps and this promotion have only run for 6 weeks, and the calculated results shows that he/she have to tap the card for 48 times a day, which is almost impossible. A loophole which many people have mis-used I guess.
