DO NON-POOR PEOPLE EVEN NOTICE WHCH BUSES ARE FREE OR NOT FREE?
City buses are run by the Bangkok Mass Transit Authority (BMTA) and trains are operated by the State Railway of Thailand (SRT),
In fact, most people who board these city buses regularly probably don't even know they are free since these buses run along the same routes with all the other buses and the words free bus don't really stand out. Taking a quick informal survey, his did seem to be the case with many people.
