The screenshot of the conversation between the driver and the prospective passenger, shared in an online post last Thursday, indicated that the latter was requesting a ride for two people and one wheelchair, AsiaOne reported.
The fare, just S$5.70, prompted the driver to send the above text message before canceling the ride.
The post went viral before it was deleted and many online commenters sided with the driver, pointing out that the passenger had not booked the GrabAssist service, which offers wheelchair assistance and specially trained staff.
When contacted by media outlet Mothership, Grab Singapore apologized for the incident, stating that the driver had acknowledged his mistake and received a warning as it was his first offense.
"This incident does not reflect the integrity and professionalism that the majority of our driver-partners uphold in accordance with our code of conduct," it said.
Nonetheless, it also recommended that passengers choose the appropriate service for their needs and reminded both drivers and passengers to treat each other with respect.
