The driver would make sure all of his customers are back into the bus before he takes off. As a foreigner not understanding much Vietnamese, it's a piece of mind that you won't be left behind when you go for your toilet/ meal break. Hảo bus' shuttle bus service is another bonus which can deliver you from the bus terminal to your accommodation for FREE! Saving you from having to wake up from the bus trip, still half dreaming and looking and bargaining for a taxi trip to your hotel.
