We took a bus ride back from Singapore to Ayer Tawar but the bus service was terrible. The seats was too upright for a 10 hours journey and the driver was smoking throughout the journey. Not only did it smell, because the window was open, it was noisy and we couldn't really sleep during the journey. It was terrible when your seat is cannot be reclined too much plus the smell and the noise. I think the bus driver is not really considerate and this is not the first time complaint like this has been filed. I'm a heavy sleeper and I usually sleep throughout my whole journey but I can't and this means that this bus ride home was really terrible.
