30 year-old immigration consultant Madelyn Ong Kim Choo was ordered to pay $5500 in compensation to 52 year-old sales promoter Sakinah Sani for attacking her on the SBS Transit service No 293 at Tampines Bus Interchange on May 12 last year.
A court heard the dispute arose when Madam Sakinah stepped aside to allow passengers behind her to board first.
As the service was full neither woman could board it so Madam Sakinah stepped back in the queue in front of Ong.
Madelyn misunderstood and thought Sakinah had cut into her queue. The two women got into an argument and Madelyn punched Sakinah.
