The price I paid included a suitcase up to 20 kg. The woman didn't want to weigh the suitcase, even though the scales were right next to her. Instead, she asked for another 20 baht. In Thai she expressed herself unfriendly. However, I understood what she said.
Fantastic bus terminal, comfortable bus, every seat numbered and perfectly punctual. Best part for me was announcements in 3 languages including English.
The driver don't allow passenger to talk at all even in normal volume, he even will stop at the side of highway for few time just to ask other people to shut up, although I didn't talk at the whole journey, but I don't felt disturb by other passenger even thought they are talking, everytime got people talking he will look at the back mirror just to give the stare to the passenger and purposely change to slow lane and drive very slow until the passenger is no longer talking then he will drive back to normal lane, he definitely is over reacting and got some anger issue, and me and my wife felt unsafe when he is driving like this, he is not suitable to become a bus driver with this anger issue he got.
