Mrs Leong, in her 40s, an executive, was on her way to Orchard Road on 5 October, and she was about to turn into Cairnhill Road when she noticed a lady in her 40s and driving an old model Mercedes Benz trying to cut into the short queue.
Mrs Leong then signalled to the driver that she should not do that.
Unhappy, the lady got down from her car and motioned to Mrs Leong to wind down her window, who then did, and Mrs Leong then explained to the driver that it was not right of her to do what she did.
The driver then mumbled an apology reluctantly, and Mrs Leong, who was in a hurry, then wound her window up. According to her, the driver continued to mumble something, then to her horror, and suddenly smashed her fist into the left side window of her car.
In a state of shock, Mrs Leong then got down from her car to speak to her, who hurriedly left the scene before she could get hold of her.
The result of this? An ugly scratch which Mrs Leong supposes was caused by a ring or hard object.
Flustered, she did not take down the licence plate of the driver, but says she is able to recognise her once she sees the driver on the road again.
