SMRT said on its Facebook page: “We apologise for the inconvenience caused to all affected passengers.”
The company added in its statement that all bus captains attend English classes to improve their ability to understand and converse in the language.
“They are also encouraged to seek help from other passengers if they do encounter communication difficulties. So please help where you can,” said SMRT.
The Facebook user also added that one of the children who paid for the bus fare was 0.86m tall.
According to TransitLink’s website, children up to a height of 0.9m who are accompanied by an adult may travel for free.
The Facebook post has been making the rounds on social media, with nearly 2,000 shares, and has received a mix of reactions from netizens.
One user, Vince Viknesh J’eg Pillay, said the ability to communicate in English should have been a basic requirement for bus captains.
“It can lead to disastrous consequences should an emergency arise and the driver is not able to communicate with the passengers,” the user commented.
