No wasting time in picking up passenger.
10minutes for toilet just nice.
But waiting experience at KL Sentral can be improve. At least allow passenger waiting in air-conditioning area. Once the bus arrive can inform the passenger to go down to platform and straight embark the bus straight away.
Safety and comfort. Bus driver gave us 5 minutes comfort stop but waited for 30 minutes at Ipoh stop
The ride is smooth and efficient, leave KL Sentral on time but arrival at butterworth is late by 15 minutes. Overall still a good value for money.
