    This morning (8.29 a.m.) when I alighted at Bus Stop 43701 from Bus No.187, immediately to see SBM 3002K driven by an Indian driver over take the 187 without slowing down as everyday many of the commuters have to transfer to No. 189 at that Bus stop to Bukit Crescent area for work. As such, we have to wait for another 10 mins. for Bus 189 (SBM 3005C) to arrive.

    As the bus is totally no packed, I am very disappointed that the driver is so impatient and just over take without slowing for other commuters to board. I hope this will not happen again.

    Regards,
