Commuter forgot to tap out on her feeder bus transfer trip and was charged a higher fare

Mdm Aishah was on her way home from Lavender. She boarded bus service 145 at Eminent Plaza and alighted at Toa Payoh bus interchange. She then transferred to feeder bus service 232 and alighted at Chung Hwa Free Clinic.
 
She was surprised to learn that her total fare from Eminent Plaza to home was $1.15. She recalled that her usual fare was $1.01
 
Explanation
 
Mdm Aishah’s fare from Eminent Plaza to home was higher than usual as she has forgotten to tap out when she alighted from the air-conditioned feeder bus service 232. Hence, she was charged the maximum chargeable distance of 3.2km for the feeder bus service, resulting in a total distance of 7.8km for her journey (4.6km on bus service 145 and 3.2km on bus service 232). Her total fare is thus $1.15.

If Mdm Aishah had tapped out upon exiting bus service 232, the fare system would have recognised her actual travelled distance of 0.8km on bus service 232. The total distance travelled would hence be 5.4km (4.6km on bus service 145 and 0.8km on bus service 232) and she would be charged her usual fare of $1.01.
